8 C.F.R. § 245.3
Any application for benefits under section 13 of the Act of September 11, 1957, as amended, must be filed on Form I-485 with the director having jurisdiction over the applicant's place of residence. The benefits under section 13 are limited to aliens who were admitted into the United States under section 101, paragraphs (a)(15)(A)(i), (a)(15)(A)(ii), (a)(15)(G)(i), or (a)(15)(G)(ii) of the Immigration and Nationality Act who performed diplomatic or semi-diplomatic duties and to their immediate families, and who establish that there are compelling reasons why the applicant or the member of the applicant's immediate family is unable to return to the country represented by the government which accredited the applicant and that adjustment of the applicant's status to that of an alien lawfully admitted for permanent residence would be in the national interest. Aliens whose duties were of a custodial, clerical, or menial nature, and members of their immediate families, are not eligible for benefits under section 13. In view of the annual limitation of 50 on the number of aliens whose status may be adjusted under section 13, any alien who is prima facie eligible for adjustment of status to that of a lawful permanent resident under another provision of law shall be advised to apply for adjustment pursuant to such other provision of law. An applicant for the benefits of section 13 shall not be subject to the labor certification requirement of section 212(a)(14) of the Immigration and Nationality Act. The applicant shall be notified of the decision and, if the application is denied, of the reasons for the denial and of the right to appeal under the provisions of part 103 of this chapter. Any applications pending with the Service before December 29, 1981 must be resubmitted to comply with the requirements of this section.
