B.D. PARKER, JR., Circuit Judge:
The New York State Department of Education and related defendants appeal from an order of the United States District Court for the Western District of New York (Siragusa,
J.)
denying their motion to vacate an award of attorney’s fees to Simon E. Kirk. The district court had awarded Kirk attorney’s fees pursuant to 42 U.S.C. § 1988(b) after he successfully challenged on equal protection grounds New York State Education Law § 6704(6), which restricts professional veterinarian licenses to United States citizens and aliens who are lawful permanent residents of the United States. The Department appealed the district court’s ruling that § 6704(6) was unconstitutional and while the appeal was pending, the United States granted Kirk permanent legal resident status, which meant that § 6704(6) no longer precluded him from obtaining the license. Accordingly, a panel of this Court dismissed the appeal as moot and vacated the judgment. The Department then moved in the district court to vacate the fee award. The district court concluded that because the judgment in Kirk’s favor, though later vacated, had brought a judicially-sanctioned, material alteration of the parties’ legal relationship that had not been reversed on the merits, Kirk was a prevailing party entitled to attorney’s fees under 42 U.S.C. § 1988(b).
Kirk v. New York State Dep’t of Educ.,
No. 08-CV-6016 (CJS),
BACKGROUND
Kirk, a Canadian citizen, is a veterinarian who, prior to December 2008, was living and working in the United States pursuant to a Trade Nafta Visa (“TN Visa”), which allowed him to stay and work in the United States temporarily. 1 Because Kirk was neither a United States Citizen nor a permanent resident alien, under New York law he was not eligible for a veterinarian license. Specifically, New York State Education Law § 6704(6), provides that “[t]o qualify for a license as a veterinarian, an applicant shall ... be a United States citizen or an alien lawfully admitted for permanent residence in the United States[.]” However, effective July 2004, Kirk obtained a temporary waiver of § 6704(6)’s requirements because there *136 was a “shortage of qualified applicants to fill existing vacancies in veterinary medicine.” N.Y. Educ. Law § 6704(6) (McKinney 2010). Thus, the State of New York granted Kirk a limited license, which allowed him to practice veterinary medicine in New York for four years. 2 The license expired in July 2008 and could not be extended. Had Kirk met the citizenship/residency requirement of § 6704(6), he would have received a permanent veterinary license, which, unlike the limited license, had no expiration date.
In January 2008, seven months before his limited license was set to expire, Kirk sued in the United States District Court for the Western District of New York pursuant to 42 U.S.C. §§ 1981 and 1983 challenging the constitutionality of § 6704(6)’s permanent residency and citizenship requirement. Specifically, Kirk alleged that the law’s requirement violated the Equal Protection and Supremacy Clauses of the United States Constitution. The parties filed cross-motions for summary judgment. In June 2008, the district court held that § 6704(6)’s citizenship/residency restriction was unconstitutional and granted summary judgment to Kirk.
Thereafter, Kirk moved for аn award of attorney’s fees pursuant to 42 U.S.C. § 1988(b). While Kirk’s application was pending in the district court, the Department appealed and also sought a stay pending appeal from the district court. The Department argued that absent a stay of enforcement of the district court’s determination that § 6704(6) was unconstitutional, the Department “would have no grounds for denying permanent lifetime licensure to [Kirk],” a result that would “irreparably injure[ ]” the Department because the license could not be revoked even if the district cоurt’s decision were overturned on appeal (except if Kirk committed an act of professional misconduct). See Frank Muñoz Deck, JA 369 ¶¶ 6, 8. Unpersuaded, the district court denied the stay. Consequently, the Department was required' to issue Kirk a permanent license, which wаs the objective of his lawsuit, and which, because of the vagaries of New York’s Education Law, could not be revoked by a reversal of the district court’s judgment. In January 2009, the district court concluded that Kirk was a “prevailing party” under § 1988 and awarded him $74,349.44 in attorney’s fees and disbursеments.
At some point prior to the end of 2008, Kirk applied for and received permanent resident status effective December 2008. Because he was now a permanent resident, § 6704(6) no longer precluded him from obtaining a permanent veterinary license. Aсcordingly, on June 24, 2009, in response to a motion by the Department, this Court dismissed the appeal as moot and vacated the judgment.
After that dismissal, the Department moved in the district court to also vacate the award of attorney’s fees, arguing that because thе judgment had been vacated, Kirk had lost his status as a “prevailing party” for purposes of § 1988. The district court denied the motion, holding that “because [Kirk] obtained a judicially-sanctioned, material alteration of the parties’ legal relationship on the merits, which wаs not later reversed on the merits, [Kirk] is a prevailing party under 42 U.S.C. § 1988(b).”
Kirk,
This appeal followed. It presents the sole legal question of whether Kirk is a prevailing party, an issue we review de
*137
novo.
See Pres. Coal, of Erie Cnty. v. Fed. Transit Admin.,
DISCUSSION
Under § 1988, when a party succeeds on a § 1983 claim, “the court, in its discretion, may allow the prevailing party ... a reasonable attorney’s fee as part of the costs.” 42 U.S.C. § 1988(b). “[Plaintiffs may be considered prevailing parties for attorney’s fees purposes if they succeed on any significant issue in litigation which achieves some of the benefit the pаrties sought in bringing suit.”
Farrar v. Hobby,
It is undisputed that Kirk initially succeeded on the merits of his claim because the district court found New York State Education Law § 6704 unconstitutional. It is equally clear that the district court’s order brought about a judicially sanctioned change in the parties’ legal relationship because it required the Department to issue Kirk a license in July 2008.
See Texas State Teachers Ass’n v. Garland Indep. Sch. Dist.,
The Department urges us to look to language in
Sole v. Wyner,
In
Sole,
an organizer of an event in which participants were to engage in a
*138
naked peaсe protest at a state beach, brought a § 1983 First Amendment action challenging the state regulation governing clothing in state parks and seeking preliminary and permanent injunctive relief.
Id.
at 78,
Critical to the Court’s analysis was the fact that the case involved a preliminary injunction that was superseded by “the eventual ruling on the merits for defendants, after both sides considered the case fit for final adjudication.”
Id.
at 84-85,
We conclude that Kirk’s situation is materially different than the plaintiffs situation in
Sole
in at least three respects. First, Kirk obtained a judgment on a fully developed record, whereas
Sole
involved an abbreviated record and a preliminary determination that was superseded by a ruling on the merits for defendants. In denying attorney’s fees for the plaintiffs success in obtaining a preliminary injunction, the Court in
Sole
emphasized the unique nature of preliminary injunctions and limited its holding to cases involving such relief.
See, e.g., id.
at 77,
Second, in this case, unlike in
Sole,
no court overturned Kirk’s favorable judgment on the merits or rejected the legal premise of the district court’s decision. The district court’s judgment was vacated only because Kirk was granted legal permanent resident status. The Court did not intend
Sole
to reach such situations.
See id.
at 86,
Finally, and most importantly, unlike the plaintiff in Sole, Kirk did not leave cоurt empty handed; he “prevailed” in June 2008 when he left with an order requiring the Department to issue him a veterinarian license. Although the judg *139 ment was vacated and the case ultimately became moot, that judicially sanctioned change remains in place to this day because, as the Department has conceded, once Kirk received the license, he was entitled to keep it, even if the judgement in his favor was subsequently vacated. Thus, even if we were to apply Sole to situations like this case where a judgment was vacated after an appeal became moot, Kirk would still be a prevailing party because he was able to keep the license he obtained as a consequence of the judgment.
Accordingly, we hold that Kirk is a “prevailing party” entitled to attornеy’s fees. 4
CONCLUSION
The order of the district court is AFFIRMED.
Notes
. In accordance with the North American Free Trade Agreement ("NAFTA”), "a citizen of Canada or Mexico who seeks temporary entry as a business person to engage in business activities at a professional level may be admitted to the United Statеs.” 8 C.F.R. § 214.6(a).
. The limited license expired on July 31, 2007, but Kirk was granted a one-time, one-year extension.
. The Department does not seem to dispute that prior to the Supreme Court’s pronouncement in
Sole,
Kirk would have been entitled to attorney's fees. Nor can it. Several cases in this Circuit prior to
Sole
have held that a plaintiff who achieves relief, even if only interim relief, does not lose prevailing party status if there is a later determination on appeal that the case is moot.
See, e.g., Haley v. Pataki,
. In. reaching this conclusion, we follow the other circuits that have addressed this issue since
Sole. See Diffenderfer v. Gomez-Colon,
