Is a certificate of identity issued by the Attorney General valid as evidence in a future case?

alien is admitted under 204(f) cannot be considered in future proceedings before the district court. A determination by the Attorney General is itself evidence, which is to be given whatever "probative force" the determination "intrinsically commands." See Universal Camera Corp. v. NLRB, 340 U.S. 474, 495, 71 S. Ct. 456, 468 (1951). See also Lim v. Mitchell, 431 F.2d 197, 199 (9th Cir. 1970) (admission to country as citizen and issuance of certificate of identity constituted evidence of citizenship in judicial proceedings).
