MR. JUSTICE CLARK delivered the opinion of the Court.
In Shaughnessy v. Pedreiro, 349 U.S. 48 (1955), we held that an alien, ordered deported by the Attorney General under the provisions of the Immigration and Nationality Act of 1952, might test the legality of such order in a declaratory judgment action brought under § 10 of the Administrative Procedure Act, 60 Stat. 243, 5 U. S. C. § 1009. The sole question to be determined here is whether the legality of an exclusion order entered under the relevant provisions of the same 1952 Act must be challenged by habeas corpus, or whether it may also be reviewed by an action for declaratory judgment under § 10 of the Administrative Procedure Act. The Court of Appeals held the latter to be an appropriate remedy. 97 U. S. App. D. C. 25, 227 F.2d 40. We granted certiorari, 351 U.S. 905, because of the importance of the question in the administration of the immigration law. We conclude that either remedy is available in seeking review of such orders. This makes it unnecessary for us to pass upon other questions raised by the parties.
Shung, a Chinese alien, presented himself at San Francisco on November 28, 1947, claiming admission to the United States under the provisions of the War Brides Act of December 28, 1945, 59 Stat. 659, 8 U. S. C. (1946 ed.) § 232. He testified under oath that he was the blood son of an American citizen who served in the United States armed forces during World War II. In January 1948 and again in February 1949, Boards of Special Inquiry held Shung inadmissible on the ground that he had not established the alleged relationship. The Board of Immigration Appeals affirmed. Shung first sought judicial review of this order by a declaratory judgment action instituted before the effective date of the Immigration and Nationality Act of 1952. His complaint was dismissed on the ground that the order was valid. Tom We Shung v. McGrath, 103 F.Supp. 507, aff'd sub nom. Tom We shung v. Brownell, 93 U. S. App. D. C. 32, 207 F.2d 132. We vacated the judgment and remanded the cause to the District Court with directions to dismiss it for lack of jurisdiction, 346 U.S. 906, on the authority of Heikkila v. Barber, 345 U.S. 229 (1953), which held that habeas corpus was the only available remedy for testing deportation orders under the Immigration Act of 1917. After the passage of the 1952 Act, Shung filed this suit seeking review of his exclusion by a declaratory judgment action. He asserts that our ruling in Pedreiro permitting deportation orders under the 1952 Act to be challenged by declaratory action requires a similar result as to exclusion orders. However, the Government contends that the Pedreiro rule does not apply in exclusion cases because of the basic differences between those actions and deportation cases. The Government also urges that the language, statutory structure, and legislative history of the 1952 Act support its contention.
At the outset the Government contends that constitutionally an alien seeking initial admission into the United States is in a different position from that of a resident alien against whom deportation proceedings are instituted.1 This, it contends, precludes general judicial review. Shung admits these substantive differences but counters that such a distinction should be without significance when all that is involved is the form of judicial action available, not the scope of review. We do not believe that the constitutional status of the parties requires that the form of judicial action be strait-jacketed. Nor should the fact that in one action the burden is on the alien while in the other it must be met by the Government afford basis for discrimination. Admittedly, excluded aliens may test the order of their exclusion by habeas corpus. Citizenship claimants who hold "certificates of identity" are required by § 360 (c) of the 1952 Act2 to test the validity of their exclusion by habeas corpus only. Respondent here neither claims citizenship nor did he hold a certificate of identity, and § 360 (c) has no bearing on this case. For a habeas corpus proceeding the alien must be detained or at the least be in technical custody, as the Government puts it. On the other hand, a declaratory judgment action requires no such basis and the odium of arrest and detention is not present. It does not follow that the absence of this condition would enlarge the permissible scope of review traditionally permitted in exclusion cases. The substantive law governing such actions would remain the rule of decision on the merits but the form of action would be by declaratory judgment rather than habeas corpus.3 We conclude that unless the 1952 Act is to the contrary, exclusion orders may be challenged either by habeas corpus or by declaratory judgment action.
The Government insists that Congress has limited such challenges to habeas corpus actions by certain language in the 1952 Act. It argues that the finality clause of the Act with respect to exclusion4 limits judicial review to habeas corpus only. The gist of that clause as to deportation cases is that "the decision of the Attorney General shall be final,"5 while in exclusion proceedings "the decision of a special inquiry officer [is] final unless reversed on appeal to the Attorney General." The Government reasons that the latter clause limits review to administrative appeal to the Attorney General and that no other form of review was intended, aside from habeas corpus, to test the alien's exclusion. It points to exceptions that even withhold administrative review in certain classes of cases as bolstering its position. It is true that subsections (b) and (d) of § 236 of the 1952 Act deny any administrative appeal on temporary exclusion in security cases as well as in those where the alien suffers a medical affliction of certain types. But to darken the meaning of the word "final" as used by Congress by giving it chameleonic characteristics is to indulge in choplogic. In fact, the regulations of the Attorney General seem to give "final" the same connotation with respect to deportation as does the Act with respect to exclusion. See 8 CFR, Rev. 1952, § 242.61 (e). Furthermore, as we pointed out in Pedreiro, such a "cutting off" of judicial review "would run counter to § 10 and § 12 of the Administrative Procedure Act." 349 U. S., at 51. "Exemptions from the . . . Administrative Procedure Act are not lightly to be presumed," Marcello v. Bonds, 349 U.S. 302, 310 (1955), and unless made by clear language or supersedure the expanded mode of review granted by that Act cannot be modified. We therefore conclude that the finality provision of the 1952 Act in regard to exclusion refers only to administrative finality.
The Government also points to certain testimony at hearings on the bill, as well as statements made on the floor in debate at the time of passage of the 1952 Act, as supporting its position. We believe, however, that Senate Report No. 1137, 82d Cong., 2d Sess.,6 and the statement of the managers on the part of the House which accompanied the Conference Report,7 reflect the intention of the Congress in this regard. The Senate Report, after reciting that a provision limiting "judicial review only through the writ of habeas corpus" had been stricken from the bill, stated that such action was not intended to "expand [the scope of] judicial review in immigration cases beyond that under existing law." (Emphasis supplied.) The House managers reported that after careful consideration of "the problem of judicial review" they were satisfied that the "procedures provided in the bill . . . remain within the framework and the pattern of the Administrative Procedure Act. The safeguard of judicial procedure is afforded the alien in both exclusion and deportation proceedings." We believe that our interpretation of the Act is in full accord with these significant reports made by those sponsoring and managing the legislation on the floor of each house of the Congress.
It may be that habeas corpus is a far more expeditious remedy than that of declaratory judgment, as the experience of Shung may indicate.8 But that fact may be weighed by the alien against the necessity of arrest and detention after which he may make his choice of the form of action he wishes to use in challenging his exclusion. In either case, the scope of the review is that of existing law.
