How have the courts treated an objection to an order of arrest for an illegal immigrant held upon a warrant of deportation?

The relator, however, insists that even if he admitted his guilt upon the hearing before the immigration officers, there was no proof whatever that he had admitted it before his entry into this country or before the issuance of the order of arrest. Assuming this to be so and that the Secretary acted altogether upon the admissions made by the relator upon the hearing, and further assuming that we have the right to go into the matter upon the theory that action without any evidence amounts to a denial of a fair hearing, still we think that the relator is not helped. It is true upon these assumptions that the allegations in the order of arrest that the relator had then admitted his guilt were unfounded. But irregularities in the order of arrest do not affect the status of an alien held upon a warrant of deportation after a fair hearing. It is even held that the fact that a warrant of deportation is based in part upon a charge not stated in the warrant of arrest is not an objection when the alien has had a fair hearing on the charge.
