United States Eichenlaub v. Shaughnessy…
“ It is difficult to imagine a reason which would have made it natural or appropriate for Congress to authorize the Attorney General to pass upon the undesirability and deportability of an alien, never naturalized, who had been convicted of espionage, but would prohibit the Attorney General from passing upon the undesirability and deportability of aliens, such as the relators in the instant cases, who had procured certificates of naturalization before their convictions of espionage, but later had been deprived of those certificates on the ground of fraud in their procurement. ”
