other actions by or against them, be deemed citizens of the States in which they are respectively located.” Act of June 25, 1948, ch. 646, § 1348, 62 Stat. 869, 934.
Though Congress did not tinker further with the citizenship of national banks after 1948, it did dramatically shift the understanding of diversity jurisdiction with respect to the citizenship of state-chartered corporations in 1958. That year, Congress enacted a provision stating that a state-chartered corporation — which includes state-chartered banks- — -is a citizen of both the state of incorporation and the state of its “principal place of business.” Act of July 25, 1958, Pub. L. No. 85-554, sec. 2, § 1332, 72 Stat. 415. That provision is now codified at 28 U.S.C. § 1332(c)(1).
The meaning of a statute’s terms is to be determined as of the time that it became law. See MCI Telecomms. Corp. v. Am. Tel. & Tel. Co., 512 U.S. 218, 228, 114 S.Ct. 2223, 129 L.Ed.2d 182 (1994). At the time that Congress employed the word “located” in § 1348, the statutory concept of “principal place of business” had not yet come into existence. Canons of statutory construction thus counsel against interpreting “located” in § 1348 as providing a basis for subject matter jurisdiction based on a national bank’s principal place of business. See WMR e-PIN, 653 F.3d at 709 (“We will not import a jurisdictional concept into § 1348 that was unknown at the time of its adoption.”).
As observed by our sister circuits, “[njothing in the current version of the statute or in its history suggests that Congress intended to revive the principle of jurisdictional parity between state-chartered banks and national banks” once it affirmatively deleted that parity from earlier versions of the statute. Rouse, 747 F.3d at 715. We agree that
when Congress introduced principal-place-of-business citizenship for state banks and corporations in § 1332(c)(1), it made no reference to jurisdictional parity, nor to national banks or § 1348. And nothing in § 1348 indicates that it would incorporate by reference any subsequent change in the statutes governing jurisdiction over state banks and corporations.
WMR e-PIN, 653 F.3d at 708.
If Congress wishes to amend § 1348, then of course it is free to do so. That task, however, is not for us. See Rouse, 747 F.3d at 715. We again share our sister circuits’ view that “should Congress wish to link the jurisdiction for national and state banks, the statute can easily be amended,” id. and that “[wjhether [jurisdictional parity between national and state banks] ought to be revived is a policy question for Congress, not the federal courts,” WMR e~ PIN, 653 F.3d at 709.
Melina argued before the District Court that OneWest’s principal place of business is in New York, and thus that there could be no diversity jurisdiction between the parties. He argued further that CIT Group’s proposed acquisition of OneWest’s parent company warranted use of CIT Group’s principal place of business instead of OneWest’s for purposes of diversity jurisdiction. The District Court rejected these arguments, concluding instead that (1) OneWest had successfully shown “that its main office and principal place of business is in California based on an affidavit submitted by Jon Dickerson, the First Vice President of its foreclosure department, and an application to the Federal Reserve System,” App. 167, and (2) “the citizenship of any actual or proposed parent of OneWest does not control OneW-est’s citizenship for purposes of diversity jurisdiction,” App. 168.
On appeal, Melina argues that “a national association is a citizen of the state of its
