(5) Labor certification and qualifications for certain immigrants (A) Labor certification (i) In general Any alien who seeks to enter the United States for the purpose of performing skilled or unskilled labor is inadmissible, unless the Secretary of Labor has determined and certified to the Secretary of State and the Attorney General that— (I) there are not sufficient workers who are able, willing, qualified (or equally qualified in the case of an alien described in clause (ii)) and available at the time of application for a visa and admission to the United States and at the place where the alien is to perform such skilled or unskilled labor, and (II) the employment of such alien will not adversely affect the wages and working conditions of workers in the United States similarly employed. (ii) Certain aliens subject to special rule For purposes of clause (i)(I), an alien described in this clause is an alien who— (I) is a member of the teaching profession, or (II) has exceptional ability in the sciences or the arts. (iii) Professional athletes (I) In general A certification made under clause (i) with respect to a professional athlete shall remain valid with respect to the athlete after the athlete changes employer, if the new employer is a team in the same sport as the team which employed the athlete when the athlete first applied for the certification. (II) “Professional athlete” defined For purposes of subclause (I), the term “professional athlete” means an individual who is employed as an athlete by— (aa) a team that is a member of an association of 6 or more professional sports teams whose total combined revenues exceed $10,000,000 per year, if the association governs the conduct of its members and regulates the contests and exhibitions in which its member teams regularly engage; or (bb) any minor league team that is affiliated with such an association. (iv) Long delayed adjustment applicants A certification made under clause (i) with respect to an individual whose petition is covered by section 1154(j) of this title shall remain valid with respect to a new job accepted by the individual after the individual changes jobs or employers if the new job is in the same or a similar occupational classification as the job for which the certification was issued. (B) Unqualified physicians An alien who is a graduate of a medical school not accredited by a body or bodies approved for the purpose by the Secretary of Education (regardless of whether such school of medicine is in the United States) and who is coming to the United States principally to perform services as a member of the medical profession is inadmissible, unless the alien (i) has passed parts I and II of the National Board of Medical Examiners Examination (or an equivalent examination as determined by the Secretary of Health and Human Services) and (ii) is competent in oral and written English. For purposes of the previous sentence, an alien who is a graduate of a medical school shall be considered to have passed parts I and II of the National Board of Medical Examiners if the alien was fully and permanently licensed to practice medicine in a State on January 9, 1978 , and was practicing medicine in a State on that date.

For purposes of clause (ii), determination of the standardized tests required and of the minimum scores that are appropriate are within the sole discretion of the Secretary of Health and Human Services and are not subject to further administrative or judicial review.
