The United States Parole Commission petitions for a writ of mandamus directing the District Court to vacate an order denying the Commission’s motion to dismiss a pending case for lack of jurisdiction. In the alternative, the Commission asks that the writ require the court to transfer the case to the Western District of Texas. 1 We conclude that the District Court did not err in asserting jurisdiction or abuse its discretion in refusing to transfer. We accordingly deny the Commission’s petition.
I. Background
The Parole Commission and Reorganization Act 2 authorizes the Commission to promulgate guidelines for determining when federal prisoners will become eligible for parole consideration. 3 The Commission’s guidelines combine an “offense se *340 verity” factor, which is a rating of the gravity of the prisoner’s crime, with a “salient factor score,” which utilizes the prisoner’s recidivistic characteristics to predict the potential risk of parole violation. 4 In 1983, the Commission revised the guidelines and upgraded the offense-severity rating of a number of crimes. In the process, breaches of the National Firearms Act, 5 all of which were formerly in the fourth or “high” category, were elevated to category five when the criminal conduct included illegal possession of a machine gun, and to category six when illegal possession of a firearm silencer was involved. 6 The effect of the reclassification is to delay parole consideration for these offenders by approximately one to four years. 7
On December 4, 1982, Stephen Pearson, the respondent, was convicted of violating the National Firearms Act by illegally possessing a machine gun and a silencer. 8 He is presently serving his nine-year sentence in a federal correctional institution in La Tuna, Texas. Following a parole hearing in April, 1984, the Commission, applying the 1983 guidelines, notified Pearson that he would be eligible for parole within 52 to 64 months from the date of his imprisonment commenced. 9 Both the Commission’s Regional Board and its National Appeals Board affirmed this determination. 10
Having thus exhausted his administrative remedies, Pearson filed a pro se application for a writ of habeas corpus in the District Court for the Western District of Texas challenging the constitutionality of the reclassification of his offense. 11 A month later, Pearson initiated identical litigation in the District Court for the District of Columbia. 12 After that court appointed counsel to represent him, Pearson amended his complaint to seek declaratory and in-junctive relief in addition to a habeas corpus writ. 13 Pearson asserts that the upgrading of the severity of firearms violations to a category including such heinous crimes as sexual exploitation of children and forcible rape violates his right to equal protection of the laws, and is arbitrary, capricious and an abuse of discretion under the Parole Commission and Reorganization Act. 14 He also asserts that application to him of the 1983 guidelines, which were not in effect when he was sentenced, infringes *341 the ex post facto prohibition of the Constitution. 15 Should Pearson prevail on these claims, he possibly could be considered for parole under the earlier guidelines, which set a presumptive parole date of 20 to 26 months, instead of 52 to 64, from the date his incarceration began. 16
The Commission moved to dismiss the case for want of jurisdiction, or in the alternative to transfer the case to the Western District of Texas. 17 The Commission argued that since Pearson seeks ultimately an earlier parole date, he is actually challenging the fact or duration of his confinement, and under the Supreme Court’s ruling in Preiser v. Rodriguez 18 can do so only through habeas corpus. 19 The court was without subject-matter jurisdiction over the habeas corpus application, the Commission insisted, because it lacked personal jurisdiction over Pearson’s immediate custodian, the warden of the penal facility in which Pearson is confined. 20 Alternatively, the Commission sought transfer of the case to the Western District of Texas, maintaining that suits filed by prisoners neither sentenced nor confined in the District of Columbia present factors that are more conveniently triable at the place of confinement, while acceptance of such suits in the District of Columbia will encourage a concentration of prisoner litigation from all over the country, and thereby impose a heavy burden on both the courts and local counsel. 21
The District Court denied the Commission’s motion. 22 The court first rejected the argument that habeas corpus was Pearson’s exclusive remedy:
Prieser [sic] specifically applied only in those cases wherein a prisoner is challenging “the very fact or duration of his confinement.” Here, plaintiff is not necessarily seeking an early release. Rather, he is seeking to have certain parole regulations declared illegal, and to have certain other parole regulations applied to his case. Thus, it could be said that he is seeking only a determination of his parole consistant [sic] with the law. Therefore, plaintiff may properly bring this action for declaratory and injunctive relief, as well as in habeas corpus. 23
The court also held that even if habeas corpus were Pearson’s sole remedy, he faced no jurisdictional barrier because the Commission, over which the court had personal jurisdiction, was Pearson’s custodian for purposes of suit; “[i]t is the Commission,” said the court, “which is the entity ‘making the decision to keep the petitioner *342 in custody,’ by applying to the petitioner its revised regulations.” 24 The court further concluded that the District of Columbia was the more convenient forum in which to litigate Pearson’s claims, pointing out that “ ‘the decision was made here, the decision makers are here, as well as any information the decision makers may have relied upon in making their determination.’ ” 25 The Commission then petitioned this court for a writ of mandamus.
II. The Motion To Dismiss
A. Review by Mandamus
Mandamus is an extraordinary remedy, to be afforded only in exceptional circumstances. 26 The Supreme Court has carefully circumscribed issuance of the writ, recognizing that it “has traditionally been used in the federal courts only ‘to confine an inferior court to a lawful exercise of its prescribed jurisdiction or to compel it to exercise its authority when it is its duty to do so.’ ” 27 As the Court has explained, “only exceptional circumstances amounting to a judicial ‘usurpation of power’ will justify the invocation of this extraordinary remedy,” 28 and the party seeking the writ must demonstrate that his right to it is “clear and indisputable.” 29
The Commission asserts that the District Court usurped judicial power by exercising jurisdiction over Pearson’s case. It argues that the District Court misconstrued Supreme Court precedent and decisions of this court in ruling that habeas corpus is not Pearson’s exclusive remedy and in considering the Commission as Pearson’s custodian for purposes of a habeas corpus challenge to the Commission’s guidelines. 30
Whether Pearson’s thesis launches an attack on the fact or duration of confinement, which under Preiser is cognizable only in a habeas corpus proceeding, 31 is not nearly as clear as the Commission would have us believe. Indeed, the District Court relied on a post-Preiser decision of this court strongly supporting the conclusion that it had jurisdiction. 32 And even if we were to conclude that the District Court simply erred in entertaining Pearson’s suit, it would not follow that mandamus lies. 33 The District Court had jurisdiction to deter *343 mine its own jurisdiction 34 and mandamus may not substitute for an appeal. 35 If lack of jurisdiction is not clear, but merely doubtful, the writ should be denied. 36
We thus have serious misgivings about the propriety of the Commission’s petition for mandamus insofar as it seeks to set for naught the District Court’s retention of Pearson’s prayer for declaratory and in-junctive relief. We need not, however, pursue the question any further. We are satisfied that there is jurisdiction to order relief of that nature, 37 though not Pearson’s release from confinement, 38 and the suitability of mandamus to test the ruling on the Commission’s motion to transfer is clear. 39
B. Exclusivity of Habeas Corpus
Pearson, we repeat, seeks declaratory and injunctive relief, contending that a 1983 parole guideline violates the Parole Commission and Reorganization Act and is unconstitutional both on its face and as applied to him. On the same theory, he has also applied for a writ of habeas corpus. 40 Jurisdiction over a habeas corpus application, however, is dependent upon the court’s authority over the petitioner’s custodian, 41 and only recently we rejected the notion, which Pearson 42 and the District Court 43 share, that the Commission may properly be viewed as the custodian of one in Pearson’s situation. 44 Rather, we held, “for purposes of challenging a Parole Commission action on the sentence a prisoner is currently serving in a federal penal facility, the warden of that facility is the prisoner’s custodian within the meaning of” the federal habeas corpus statute. 45 It follows that, if habeas corpus is Pearson’s exclusive remedy, as the Commission insists, declaratory and injunctive relief would for that reason be unavailable to him, and the District Court would be unable to consider his claims in a habeas corpus proceeding because it lacks jurisdiction over his custodian.
—(1) The Preiser Decision
Addressing, then, the question whether Pearson is restricted to habeas corpus in his quest for a judicial ruling on the validity of the guideline under attack, our starting point is the Supreme Court’s decision in Preiser v. Rodriguez. 46 There, three inmates of state prisons instituted Section 1983 actions, 47 joined with applications for writs of habeas corpus, challenging the deprivation of goodtime credits in prison *344 disciplinary proceedings allegedly violative of their rights to due process and equal protection of the laws. The sole relief requested was an injunction restoring the credits, which in each case would have resulted in immediate release from prison because the conditional-release dates for all three had passed. 48
After analyzing the history and function of the Great Writ, the Court noted that “the essence of habeas corpus is an attack by a person in custody upon the legality of that custody, and ... the traditional function of the writ is to secure release from illegal custody.” 49 Challenges to the fact or length of imprisonment coupled with prayers for earlier or immediate release therefrom, the Court held, were at the “core” 50 and “heart” 51 of habeas corpus, and assertable only in habeas corpus proceedings:
[W]hen a state prisoner is challenging the very fact or duration of his physical imprisonment, and the relief he seeks is a determination that he is entitled to immediate or speedier release from that imprisonment, his sole federal remedy is a writ of habeas corpus. 52
The inmates’ attack on the deprivation of their good-time credits fell within the established scope of habeas corpus because withholding the credits “was causing or would cause them to be in illegal physical confinement ... once their conditional-release date had passed.” 53
Under Preiser, then, habeas corpus is the exclusive remedy for a prisoner attacking the “fact or duration” of confinement and demanding “immediate or speedier release” from custody. The Court gave some indication, however, of the parameters of Preiser’s holding by distinguishing situations outside the ambit of habeas corpus in which a prisoner could obtain relief of another character. A prisoner suing for damages, the Court declared, cannot resort to habeas corpus, 54 nor is it necessary that litigation over the conditions of prison life *345 proceed in habeas corpus. 55 Thus the Preiser Court contemplated that habeas corpus would be a prisoner’s single remedy-in some situations, but an alternative or unavailable remedy in others.
Just a year after Preiser, the Court shed further light upon the reach of that decision. In Wolff v. McDonnell, 56 an inmate of a state prison brought a Section 1983 class action alleging, among other things, that the prison’s disciplinary regime, which had led to cancellation of some of the inmate’s good-time credits, did not comport with due process. As relief, the action sought restoration of the credits, a plan for a due process hearing procedure in connection with withholding and forfeiture of such credits, and damages for denial of civil rights resulting from use of the existing disciplinary procedure. 57 Addressing “[a]t the threshold ... the issue whether under Preiser ... the validity of the procedures for depriving prisoners of good-time credits may be considered in” a Section 1983 suit, 58 the Court noted that, while Preiser foreclosed any actual restoration of credits in a nonhabeas action, 59 it also established the impropriety of using habeas corpus as a remedy for damages. 60 Consequently, the Court said, the inmate’s damages claim was properly presented in his Section 1983 action and, in turn, “required determination of the validity of the procedures employed for imposing sanctions, including loss of good time, for flagrant or serious misconduct,” 61 and therefore “[s]uch a declaratory judgment as a predicate to a damages award would not be barred by Preiser.” 62 The Court went further to explain that “because under [Preiser ] only an injunction restoring good time improperly taken is foreclosed, neither would it preclude a litigant with standing from obtaining by way of ancillary relief an otherwise proper injunction enjoining the prospective enforcement of invalid prison regulations.” 63 Accordingly, the Court “conclude[d] that it was proper ... to determine the validity of the procedures for revoking good-time credits and to fashion appropriate remedies for any constitutional violations ascertained, short of ordering the actual restoration of good time already canceled.” 64
As we read Wolff, the Court did not restrict this endorsement of injunctive relief to cases in which damages are sought. Of course, since damages claims are outside the purview of habeas corpus, Preiser presents no impediment to a declaration of invalidity of disciplinary procedures as the basis for an award of damages. But the limited injunction that the Court sanctioned was wholly unrelated to such an award; rather, it was an additional and completely different method of redressing the allegedly unconstitutional disciplinary procedures, and obviously an unavailable remedy had it been intercepted by the holding in Preiser. The only explanation for the Court’s approval of injunctive relief from the procedures was, as the Court stated, that Preiser forebade “only an injunction restoring good time improperly taken.” 65 It followed, then, that the declaration underpinning an award of damages for the use of those procedures could also serve as *346 the foundation of an injunction restraining further resort to them. 66
Even more fundamentally, Preiser did not rule that every claim that could be pressed in a habeas corpus proceeding can be advanced only in such a proceeding. 67 On the contrary, Preiser’s holding is limited explicitly to cases that are of the “essence,” or at the “core” or “heart,” of habeas corpus 68 — cases challenging “the very fact or duration of [a prisoner’s] physical imprisonment” and seeking “a determination that he is entitled to immediate release or a speedier release from that imprisonment.” 69 An action for declaratory or injunctive relief from a continuing violation of a prisoner’s rights is not invariably of that nature, and the action before us definitely is not. Pearson’s suit focuses on the guideline pursuant to which his offense was upgraded to a higher level of severity for purposes of parole eligibility. One of its requests is for an order declaring the guideline invalid and an injunction restraining its enforcement. In this aspect, the suit does not “go[] directly to the constitutionality of his physical confinement itself,” 70 nor does it ask for “a determination that he is entitled to immediate release or a speedier release from ... imprisonment.” 71
Success in this much of Pearson’s endeavor would not automatically hasten his departure from prison. It would, of course, necessitate a redetermination of his parole-eligibility date, but an earlier date would by no means be assured. Should the current guideline be invalidated, the Commission would not inexorably be required to resort to the older guideline; it could promulgate a new guideline, or it could exercise its discretion without the benefit of any guideline at all. It could review Pearson’s ease and leave his present parole-eligibility date undisturbed simply by acting outside the guidelines. 72 Thus, neither a determination that the guideline in question is invalid nor an order barring its future application would usurp “the traditional function of the writ [of habeas corpus] ... to secure release from illegal custody.” 73
*347 —(2) The Circuit Decisions
Our analysis of Preiser is in complete accord with its earlier treatments by this court, and is strongly supported by an impressive array of decisions in other circuits. We have approved a mandamus action as an appropriate proceeding by an inmate of a distant federal prison who sought “a ruling on federal parole eligibility policies applicable throughout the country.” 74 The inmate, we said,
did not challenge the fact or duration of his confinement. Rather, he asked for earlier eligibility for parole consideration. Consequently, he was not required to bring his claim as a habeas action. 75
We have also permitted a suit for an injunction compelling compliance with statutorily required procedures in parole rule-making, 76 and an action seeking disclosure of parole documents. 77 In neither of the latter two cases did we deem it necessary even to mention Preiser. 78
A number of our sister circuits have similarly concluded that a federal prisoner is not restricted to habeas corpus when his claim is that parole action violates constitutional or statutory standards and the ruling thereon will not automatically effect a release from incarceration. The First Circuit has held that habeas corpus is not the exclusive avenue to relief when the “plaintiff [does] not seek release from detention
but simply an order mandating a probable cause hearing.” 79 The Second Circuit distinguishes challenges to denials of parole from challenges to the way in which they are reached, declaring that “the manner of parole decision-making, not its outcome ... does not present a complaint of the sort in Preiser v. Rodriguez ... for which habeas corpus would be appropriate.” 80 Thus, a prisoner’s allegations that the United States Parole Board, the Commission’s predecessor, failed to comply with its own regulations, employed constitutionally deficient procedures, and reached arbitrary and unlawful conclusions would, if proven, support issuance of a writ of mandamus. 81 The court has explained:
A petition challenging parole procedures but not demanding release or the granting of parole differs from the petitions before the Court in Preiser v. Rodriguez in an important respect. Although the relief sought by petitioner may improve his chances for parole, the question of his release and of the length of his confinement still lies within the sound discretion of the board, unlike Preiser where the restoration of good-conduct-time-credits would have resulted automatically in the shortening of the prisoner’s confinement. 82
The Third Circuit, analyzing Preiser in light of Wolff, has held that Preiser does *348 not preclude a class representative from obtaining a judgment declaratory of the invalidity of parole guidelines and an injunction against their application to prisoners’ parole applications. 83 The class was not restricted to habeas corpus, the court said, because “[t]he class does not demand that its members be released on parole, but only that the Parole Board not utilize the guidelines in evaluating future parole applications.” 84 The Fourth Circuit has held that due process objections to parole-eligibility proceedings could be litigated under Section 1983, 85 explaining that the “plaintiffs disclaim that the purpose of their suits is to effect their release or to shorten the duration of their confinement” and consequently that “we do not deem this is a case where the suits were close to the core of habeas corpus.” 86 The Fifth Circuit has at least twice held that attacks on the validity of parole procedures can be made in non-habeas suits, 87 and the Seventh Circuit has found Preiser inapplicable to a prisoner’s suit for his trial transcript and damages on the ground that its connection with the prospect of release through a successful appeal was “too tenuous.” 88
These decisions furnish solid support for our interpretation of Preiser and our conclusion that it does not bar Pearson’s bid for a judgment declaring the guideline in question invalid and an injunction compelling the Commission to disregard it in resetting his parole-eligibility date. This would accomplish no more than an eventual redetermination of his parole-eligibility date in conformity with constitutional and statutory requirements. Pearson’s challenge thus is to the manner in which the decision on his eligibility date was reached, and a successful outcome would not automatically terminate or shorten the period of his confinement. Pearson’s prospects for earlier parole may brighten if he prevails, but the time at which he would actually become eligible for parole consideration would remain subject to the Commission’s discretion. Our sister circuits would agree that Pearson is not restricted to ha-beas corpus, but may proceed with his action for declaratory and injunctive relief.
III. The Motion to Transfer
The Commission predicates its mandamus petition additionally on the ground that the District Court erred in denying the Commission’s motion to transfer Pearson’s case to the Western District of Texas, wherein he is incarcerated. Judicial discretion to transfer federal civil litigation undoubtedly is broad, 89 but certainly it is not unbridled, 90 and a writ of mandamus will lie if discretion is abused. 91
*349 In Starnes v. McGuire 92 this court, sitting en banc, identified factors legally significant in determining whether a transfer of a prisoner’s civil suit is warranted. 93 Factors weighing in favor of transfer include the difficulty of communicating with counsel, the burden of transferring the prisoner, the availability of witnesses and files, the capacity to expedite final resolution, and whether the complaint sounds in habeas corpus. 94 On the other hand, needs for the testimony of witnesses residing in or near the District of Columbia and the production of documents located here favor retention of the suit. 95 Disregard of these factors may amount to an abuse of discretion justifying issuance of a writ of mandamus. 96
The District Court’s terse explanation of its rejection of the Commission’s motion for transfer falls considerably short of what we contemplated when we supplied guidelines for judges to observe. 97 Nevertheless, after analyzing the court’s supporting memorandum in its entirety, we cannot say that the court fatally misapplied the criteria laid out in Starnes. The court found that the factual inquiries summoned by Pearson’s contentions could better be pursued in the District of Columbia than in Texas, explaining that “ ‘the decision was made here, the decision makers are here, as well as any information the decision makers may have relied upon in making their determinations.’ ” 98 This conclusion relates directly to two of the Starnes factors. We recognized in Starnes that, although in some eases witnesses and files would be more accessible at the place of confinement, in other instances it would be necessary to obtain testimony and documents from officials located in the District of Columbia. 99 The District Court’s statement indicates sufficiently that it weighed these two factors and found that the balance tips in favor of retention. The court’s ruling seems to have also involved consid *350 eration of difficulties associated with transfer of the prisoner when he needs to testify, a third factor articulated in Starnes. 100 Having found that the case will revolve around the testimony of officials located here, rather than testimony of Pearson or Texas officials, the court apparently viewed that factor as disfavoring transfer, and in any event the record reveals its significance.
The District Court did discuss, and reject, a fourth factor identified in Starnes, which otherwise would have called for transfer. We pointed out in Starnes that many prisoners’ suits ostensibly for mandamus writs or for declaratory judgments actually sound in habeas corpus and therefore should be brought in the court having jurisdiction over the prisoner’s immediate custodian. 101 The District Court held, however, as have we, that Pearson was not limited to habeas corpus in his bid for declaratory and injunctive relief. 102 Although the court addressed this factor only in the jurisdictional context, 103 it obviously could not have supported a decision to transfer. The court did not allude to any difficulty Pearson might encounter in communicating with counsel or to any impediment to speedy resolution of the case. While these two factors were articulated in Starnes, they are, in the totality of circumstances here, too weak to make out a case for transfer. Considering the factors upon which the court did rely, we cannot say that it so far disregarded the criteria laid out in Starnes as to justify issuance of the sought-after writ.
The District Court did not err in retaining jurisdiction over Pearson’s claims. Nor did it abuse its discretion in refusing to transfer the case. The Commission’s petition for a writ of mandamus is accordingly denied.
So ordered.

. After finding that it had jurisdiction to hear Pearson’s claims, the District Court summarily declared:
Nor will the Court grant defendant’s motion to transfer under 28 U.S.C. § 1404. That section allows transfers only to a district where the action might have otherwise been brought, and "for the convenience of parties and witnesses, in the interest of justice.” For the reasons set forth above this is the most appropriate forum in terms of where the decision makers and the custodian entity are found.
Order, supra note 21, at 5, R.App. (6)6 (citation omitted). The "reasons set forth above" are discernible only from the court’s discussion of the jurisdictional problem.

. The court declared that “[f]or the reasons set forth above this is the most appropriate forum in terms of where the decision makers and the custodian entity are found." Order, supra note 21, at 5, R.App. (6) 6. The statement, "for the reasons set forth above," is ambiguous, but appears to refer to the court’s explanation of its conclusion that Preiser did not present an obstacle.
