OPINION OF THE COURT
This case is before us on a petition by the United States for a writ of mandamus directing a District Judge of the Eastern District of Pennsylvania to vacate his order transferring this criminal action against defendant Ruth Streeval to Tennessee and to refrain from transferring the case unless the showing and findings re *382 quired by Fed.R.Crim.P. 21(b) have been made. At issue before us is not the discretionary decision to transfer vel non but the procedure to be followed before such a transfer order is entered.
I.
BACKGROUND
On August 17, 2000, Ruth Streeval and Lollie Binkley, Streeval’s sister, were charged by a grand jury sitting in the Eastern District of Pennsylvania in a nine-count indictment with mail fraud, wire fraud, conspiracy to commit mail fraud, wire fraud, and money laundering, and aiding and abetting. Binkley was also charged with money laundering and criminal forfeiture. Streeval was, by agreement, arraigned near her residence in the Middle District of Tennessee due to her alleged poor health. She subsequently filed a motion for severance and transfer. The judge then presiding denied the motion on February 9, 2001.
Binkley pled guilty to all counts charged, and was sentenced to twenty-seven months imprisonment, supervised release, and payment of restitution. On May 7, 2001, Streeval, who pled not guilty, renewed her motion for severance and transfer to Tennessee. On May 8, 2001, the District Judge who now presided granted the renewed motion. On May 16, 2001, after a six-day stay, the District Court denied the government’s request for reconsideration of the motion to transfer. On June 18, 2001, the government sought a writ of mandamus to compel the District Court to reconsider its order transferring this case to Tennessee.
In the interim, on May 29, 2001, in accordance with Fed.R.Crim.P. 21(c), the Middle District of Tennessee received from the Eastern District of Pennsylvania a copy of the order severing and transferring the case, the original record of this case, and Streeval’s indictment, which in turn was filed in Tennessee. The case was docketed as 01-CR-84 and assigned to Judge Todd Campbell, who scheduled the case for prompt trial. After Judge Campbell was advised of the challenge to the transfer and this court’s decision to hear argument on the matter, he rescheduled the trial date to February 26, 2002. 1

DISCUSSION
A. Jurisdiction
The most hotly contested issue, and the one that gives us the most pause, is that of our remaining jurisdiction. Of course, the District Court originally had jurisdiction over the criminal case pursuant to 18 U.S.C. § 3231. This court has jurisdiction over a petition for a writ of mandamus pursuant to 28 U.S.C. § 1651(a). Streeval and the District Court 2 argue that courts of this circuit no longer retain jurisdiction in this case because it has been transferred to Tennessee.
*383
Fed.R.Crim.P. 21(b), the rule that Streeval invoked in seeking transfer, provides that “[f]or the convenience of parties and witnesses, and in the interest of justice, the court upon motion of the defendant may transfer the proceeding as to that defendant or any one or more of the counts thereof to another district.” 'We have interpreted the comparable civil rule to mean that when a transfer of a case has been completed, “ ‘the transferor court— and the appellate court that has jurisdiction over it — lose all jurisdiction over the case.’ ”
White v. ABCO Eng’g Corp.,
The government argues that this court retains jurisdiction because “the only document of legal significance, the indictment, remains in [the Eastern District of Pennsylvania].” Br. of Government at 7. Although a copy of the indictment was sent to the Middle District of Tennessee, the indictment was retained because Streeval’s co-defendant had pled guilty and her sentencing had not been concluded at that time. App. at 12-13. We need not evaluate this argument in light of far more compelling considerations. 3
The government argues, and we agree, that this court retains jurisdiction for purpose of evaluating the legitimacy of the transfer. In
White,
a magistrate judge in the Southern District of New York attempted to transfer a case to the District of New Jersey under 28 U.S.C. § 1404(a) by writing “so ordered” under a stipulation signed by the judge and the parties. This court determined that such an “inter-district transfer by stipulation” was invalid.
White,
The justification for this rule is clear. A district court cannot divest an appellate court of jurisdiction by the mere expedient of ordering a transfer of the file documents to any other district court without following procedures established for such a transfer. The proposition is not a new one. Indeed, we have asserted in numerous cases our retention of jurisdiction for purposes of evaluating the legitimacy of a transfer.
See, e.g., Solomon v. Cont’l Am. Life Ins. Co.,
This is not to say that an appellate court indefinitely maintains jurisdiction for purposes of evaluating the effectiveness of a transfer. Obviously, once the transferee court proceeds with the transferred case, the decision as to the propriety of transfer
ls,
to be made in the transferee court. However, it is preferable that there be a process that allows for prompt review of the transfer by the court of appeals of the transferor circuit. To accomplish that, some courts have adopted a standard procedure of automatically granting a stay of a transfer for a specified period of time. For example, the Eastern District of Pennsylvania, following a suggestion of this court in
Swindell-Dressler,
B. Suitability of Mandamus
We turn to consider whether mandamus is an appropriate means to review the transfer in this case. In general, an order transferring a case is not a final order and, hence, not appealable.
See, e.g., Nascone v. Spudnuts, Inc.,
This court has held that a writ of mandamus may issue to compel a district court to vacate an order transferring a case to another district.
Plum Tree, Inc. v. Stockment,
C. The Motion to Transfer
In deciding whether a writ of mandamus should issue with respect to an order to transfer, we must take into consideration that, other than mandamus, the petitioner has no means of adequate relief,
Mallard v. United States Dist. Court,
In support of its petition, the government focuses on three cases decided by this court:
Swindell-Dressler, Solomon
and
Plum Tree.
In
Swindell-Dressler,
a district judge “of his own volition and without any motion or petition by one or any of the parties, and without hearing, and without giving Swindell notice or opportunity to be heard, ... transferred [the case] to the United States District Court for the Northern District of West Virginia.”
Swindell-Dressler,
In
Solomon,
we were again presented with a petition for mandamus as to an order by the district judge transferring a case seeking recovery on various insurance policies to the Middle District of North Carolina, which was the situs of the accident that was the subject of the suit. This court interpreted
Swindellr-Dressler
as holding that “when the district court has acted without following appropriate procedural safeguards, we will by the writ [of mandamus] confine it in exercising that discretion to the narrow path of due process.”
Solomon,
In
Plum Tree,
the district court granted defendants’ motion for a transfer to the United States District Court for the Southern District of Texas, even though defendants did not file any supporting documents to show that a transfer would be appropriate. Plaintiffs, who strongly opposed the transfer, filed a petition for a writ of mandamus. We agreed with plaintiffs, commenting that “there was no evidence before the district court upon which it could base a finding that a transfer order was justified.”
names and addresses of witnesses whom the moving party plans to call, ... affidavits showing the materiality of the matter to which these witnesses will testify, statements by the moving partfy] of the business difficulties or personal hardships that might result from ... having to defend against the suit in the district court where it was originally brought, affidavits concerning the relative ease of access to sources of documentary evidence, and other materials where appropriate.
Id. at 757 n. 2. Because the district court did not have before it adequate grounds for ordering a transfer, we ordered that it vacate the order “without prejudice to the right of defendants on remand to renew in the district court their motion for transfer, with appropriate supporting documents.” Id. at 757.
Of the cases decided by this court, Plum Tree is most similar to the present case. Streeval, the party requesting transfer, did *387 not present “affidavits, depositions, [or] stipulations,” id. at 756, and the District Court did not hold a hearing concerning the motion to transfer at which Streeval had the burden to establish the appropriateness of transfer and the government had the opportunity to respond to Streeval’s arguments for transfer.
Streeval argues that in contrast to Plum Tree, there was evidence in the present case to support the transfer order. She refers in particular to the fact that the government did not oppose her motion to be arraigned in Tennessee, noting that the FBI had observed that she appeared at her arraignment in a wheelchair, and that not only is she herself handicapped but that she is the caretaker for her ill husband. She points out that the government’s list of witnesses filed in the Eastern District of Pennsylvania included only some witnesses from the Philadelphia area but also some from Tennessee and others that are geographically dispersed. She also asserts, but without specificity, that any evidence for the defense would be located in Tennessee, and notes that none of the offenses is alleged to have been committed in Pennsylvania. App. at 29-30.
Because the government abjures arguing the merits of the transfer, its focus is on the procedure followed by the District Court before it ordered the transfer. Whether to transfer a case is generally committed to the discretion of the district courts.
See Piper Aircraft Co. v. Reyno,
On the other hand, the case law suggests that there are certain minimum procedures that should be followed before ruling on a motion to transfer. It would appear evident that the party objecting to transfer must be given an opportunity to rebut the arguments and the evidence, if any, offered by the movant in favor of transfer. Also, it is helpful when the district court provides a statement of reasons for granting the motion to transfer so that the appellate court has a basis to determine whether the district court soundly exercised its discretion and considered the appropriate factors.
See generally United States v. Criden,
Most important is that the district court’s explanation for the transfer demonstrate that the court recognized the nature of the showing that must be made to support a transfer and the parties’ respective burdens. In
Platt v. Minnesota Mining & Mfg. Co.,
(1) location of [the] ... defendant; (2) location of possible witnesses; (3) location of events likely to be in issue; (4) location of documents and records likely to be involved; (5) disruption of defen *388 dant’s business unless the case is transferred; (6) expense to the parties; (7) location of counsel; (8) relative accessibility of [the] place of trial; (9) docket condition of each district ... involved; and (10) any other special elements which might affect the transfer.
Id.
at 243-44,
As to the burdens of proof, this court has stated in 28 U.S.C. § 1404(a) cases that “[t]he burden is on the moving party to establish that a balancing of proper interests weigh in favor of the transfer.”
Shutte v. Armco Steel Corp.,
It is not surprising given the similarity between the language of § 1404(a) providing the standard governing transfer of civil cases (“[f|or the convenience of parties and witnesses, in the interest of justice”) and that of Rule 21(b) governing transfer of criminal cases (“[f]or the convenience of parties and witnesses, and in the interest of justice”), that the courts have held that the criminal defendant has the burden of making the case for transfer.
See, e.g., United States v. Spy Factory,
Inc.,
It is important not to overlook the Supreme Court’s statement in
Platt
that a defendant is not entitled to defend his case in his or her home district.
See Platt,
In this case, the government complains that the District Court granted Streeval’s motion for a transfer, even before the government received a copy of the motion, without waiting for the government’s response, and that the court acted by filing a one-line order that gave no reasons for the transfer. While the government’s frustration is understandable, these omissions would not in themselves warrant mandamus. Under the procedure in Swindell-Dressler, the government had an opportunity to put forth its argument in opposition to the transfer in its motion for reconsideration. Admittedly, it may be more difficult to persuade a judge that a decision already made to transfer the case should be vacated than it would have been to persuade the judge ^hot to transfer in the first instance, but nothing in the record suggests that the District Court did not consider the government’s arguments on reconsideration.
Similarly, while the initial transfer order dated May 8, 2001 was devoid of explanation for the decision, and the second order dated May 16, 2001 merely denied the motion to reconsider the transfer order, again without explanation, the District Court did use the vehicle of our Local Rule 3.1 to file an explanatory Memorandum dated June 19, 2001. Once again, the sparseness of the prior orders does not warrant mandamus in light of the subsequent attempt to fill the vacuum. Mandamus is only appropriate when the district court has committed a clear abuse of discretion or clear error of law.
On the other hand, it is the government’s complaint that the District Court ordered the case transferred without requiring Streeval to bear the burden of establishing that transfer was appropriate that causes us concern. Although the District Court referred to many of the relevant factors, if in fact the court was unaware that the burden to show reasons for the transfer was on the defendant, then the misconception would be serious enough to warrant mandamus. The burden of proof is often the determinative factor in a discretionary decision, particularly in one where the factors may be closely balanced. It is important that an appellate court performing its review function be satisfied that the district court recognized where the burden lay. Here, Streeval has not pointed to anything in the record or in the District Court’s memorandum that indicates that the District Court placed the burden on Streeval. The government complains, for example, that Streeval has neither identified nor produced documents that allegedly show relevant activities took place in Tennessee; that she has not identified witnesses in Tennessee whereas it has, such as Wentworth, one of the principal victims of the fraud, who is in or near the Eastern District of Pennsylvania; and that she has not produced adequate evidence that it would be physically burdensome for her to be tried in Philadelphia.
We recognize that the District Court may indeed have placed the burden on Streeval and have balanced the factors to reach its decision to transfer the case to the Middle District of Tennessee, but we have no basis to so hold on the record before us. Under the circumstances, we will remand this matter to the District Court for reconsideration, requiring Streeval to bear the burden of showing why transfer is appropriate. We express no opinion as to the merits of a transfer. At argument the government conceded that once the District Court evaluated the factors in light of the appropriate burden, there would be no basis for it to file another mandamus petition.
In light of the scheduled trial date in Tennessee and our desire to be reciprocal *390 ly accommodating to the District Court in Tennessee, we will direct the District Court on remand to require the parties promptly to present their arguments and supporting data, and to rule no later than the end of the calendar year. 7
III.
CONCLUSION
Because we cannot be sure that the District Court followed appropriate procedure before transferring this case to Tennessee, we will issue a writ of mandamus ordering the District Judge to reconsider Streeval’s motion to transfer in accordance with the procedure set out in this opinion.
Notes
. We are most appreciative of Judge Campbell's accommodation, which enabled this court to consider the matter and prevented an unseemly tension between federal jurisdictions. We undertook to rule on the appeal as promptly as possible.
. The District Court, exercising the option accorded to it by 3rd Cir. R. 3.1 (2001), which allows a district judge to file an opinion or memorandum to explain an order or decision after an appeal is taken, filed a memorandum that, in addition to summarizing the reasons for transfer, includes arguments why this court should not grant mandamus, more akin to an adversarial brief of a party than a "written amplification” of a prior order for which the Rule is designed.
. The government also argues that the transfer was invalid because the District Court's order transferred the case to the "non-existent ‘District of Tennessee.' " Br. of Government at 14. Although the District Court did not specify to which of the three judicial districts in Tennessee the case was being transferred, it was clear from the context of this case and the fact that Streeval was arraigned in the Middle District of Tennessee that the Middle District was the intended transferee district; indeed, the court clerk did send the relevant papers to that district. The government does not cite any case that suggests that a transfer will be invalidated on such a minor technical point and we are not persuaded by this aspect of the government's argument.
. While all these cases are civil cases and thus involved transfer under 28 U.S.C. § 1404(a), as noted above, the language in rule 21(b) is analogous to § 1404(a).
.
See, e.g.,
D. Conn. R. Civ. P. 18 (directing the court clerk to wait until the
eleventh day
following the order of transfer to mail the papers); S.D. & E.D.N.Y.R. Civ. P. 83.1 (requiring the court clerk to wait five days before transferring a case to another district);
see also Roofing & Sheet Metal Servs., Inc. v. La Quinta Motor Inns, Inc.,
.
See also United States v. French,
. At oral argument, Streeval's counsel informed the court that her client was in the hospital and would be unable to attend an evidentiary hearing in Philadelphia. While regrettable, we do not regard this as a basis for delay. It is not necessary that the District Court hold an evidentiary hearing before ruling. Streeval may seek to meet her burden as to the transfer by submission of affidavits attesting to her medical condition and her inability to travel to a criminal trial in Philadelphia.
