In Bufalino v. I.&N.S., (3 Cir., 1973), 473 F.2d 728, 731, the Third Circuit held that an alien had meaningfully interrupted his residence when he knowingly made a false claim of United States citizenship upon his return to this country following trips to Bimini and Cuba. The court did not inquire into the time when the alien had formed the intent to contravene this immigration policy.
