(a) Pursuant to the authority contained in section 211(b) of the Act, an alien previously lawfully admitted to the United States for permanent residence who, upon return from a temporary absence was inadmissible because of failure to have or to present a valid passport, immigrant visa, reentry permit, border crossing card, or other document required at the time of entry, may be granted a waiver of such requirement in the discretion of the district director if the district director determines that such alien:
(1) Was not otherwise inadmissible at the time of entry, or having been otherwise inadmissible at the time of entry is with respect thereto qualified for an exemption from deportability under section 237(a)(1)(H) of the Act; and
(2) Is not otherwise subject to removal.
(b) Denial of a waiver by the district director is not appealable but shall be without prejudice to renewal of an application and reconsideration in proceedings before the immigration judge.
