Every alien (other than a nonimmigrant described in subparagraph (H)(i) or (L) of section 1101(a)(15) of this title) shall be presumed to be an immigrant until he establishes to the satisfaction of the consular officer, at the time of application for a visa, and the immigration officers, at the time of application for admission, that he is entitled to a nonimmigrant status under section 1101(a)(15) of this title. An alien who is an officer or employee of any foreign government or of any international organization entitled to enjoy privileges, exemptions, and immunities under the International Organizations Immunities Act (22 U.S.C. 288 et seq.), or an alien who is the attendant, servant, employee, or member of the immediate family of any such alien shall not be entitled to apply for or receive an immigrant visa, or to enter the United States as an immigrant unless he executes a written waiver in the same form and substance as is prescribed by section 1257(b) of this title.
A visa shall not be issued under the provisions of section 1101(a)(15)(K) of this title until the consular officer has received a petition filed in the United States by the fiancee and fiance of the applying alien and approved by the Attorney General. The petition shall be in such form and contain such information as the Attorney General shall, by regulation, prescribe. It shall be approved only after satisfactory evidence is submitted by the petitioner to establish that the parties have previously met in person within 2 years before the date of filing the petition, have a bona fide intention to marry, and are legally able and actually willing to conclude a valid marriage in the United States within a period of ninety days after the alien's arrival, except that the Attorney General in his discretion may waive the requirement that the parties have previously met in person. In the event the marriage with the petitioner does not occur within three months after the entry of the said alien and minor children, they shall be required to depart from the United States and upon failure to do so shall be deported in accordance with sections 1252 and 1253 of this title.
Notwithstanding any other provision of this chapter, an alien who is a citizen of Canada and seeks to enter the United States under and pursuant to the provisions of Annex 1502.1 (United States of America), Part C - Professionals, of the United States-Canada Free-Trade Agreement to engage in business activities at a professional level as provided for therein may be admitted for such purpose under regulations of the Attorney General promulgated after consultation with the Secretaries of State and Labor.
The fact that an alien is the beneficiary of an application for a preference status filed under section 1154 of this title or has otherwise sought permanent residence in the United States shall not constitute evidence of an intention to abandon a foreign residence for purposes of obtaining a visa as a nonimmigrant described in subparagraph (H)(i) or (L) of section 1101(a)(15) of this title or otherwise obtaining or maintaining the status of a nonimmigrant described in such subparagraph, if the alien had obtained a change of status under section 1258 of this title to a classification as such a nonimmigrant before the alien's most recent departure from the United States.
