(a) Subparts A, B, and C—(1) General. Subparts A, B, and C of this part set out the procedures adopted by the Secretary to secure information sufficient to make factual determinations of: (i) Whether U.S. workers are available to perform temporary employment in the United States, for which an employer desires to employ nonimmigrant foreign workers, and (ii) whether the employment of aliens for such temporary work will adversely affect the wages or working conditions of similarly employed U.S. workers. These factual determinations (or a determination that there are not sufficient facts to make one or both of these determinations) are required to carry out the policies of the Immigration and Nationality Act (INA), that a nonimmigrant alien worker not be admitted to fill a particular temporary job opportunity unless no qualifed U.S. worker is available to fill the job opportunity, and unless the employment of the foreign worker in the job opportunity will not adversely affect the wages or working conditions of similarly employed U.S. workers.

(2) The Secretary's determinations. Before any factual determination can be made concerning the availability of U.S. workers to perform particular job opportunities, two steps must be taken. First, the minimum level of wages, terms, benefits, and conditions for the particular job opportunities, below which similarly employed U.S. workers would be adversely affected, must be established. (The regulations in this part establish such minimum levels for wages, terms, benefits, and conditions of employment.) Second, the wages, terms, benefits, and conditions offered and afforded to the aliens must be compared to the established minimum levels. If it is concluded that adverse effect would result, the ultimate determination of availability within the meaning of the INA cannot be made since U.S. workers cannot be expected to accept employment under conditions below the established minimum levels. Florida Sugar Cane League, Inc. v. Usery, 531 F. 2d 299 (5th Cir. 1976).

(3) Construction. This part and its subparts shall be construed to effectuate the purpose of the INA that U.S. workers rather than aliens be employed wherever possible. Elton Orchards, Inc. v. Brennan, 508 F. 2d 493, 500 (1st Cir. 1974), Flecha v. Quiros, 567 F. 2d 1154 (1st Cir. 1977). Where temporary alien workers are admitted, the terms and conditions of their employment must not result in a lowering of the terms and conditions of domestic workers similarly employed, Williams v. Usery, 531 F. 2d 305 (5th Cir. 1976); Florida Sugar Cane League, Inc. v. Usery, 531 F. 2d 299 (5th Cir. 1976), and the job benefits extended to any U.S. workers shall be at least those extended to the alien workers.

(b) Subparts D and E. Subparts D and E of this part set forth the process by which health care facilities can file attestations with the Department of Labor for the purpose of employing or otherwise using nonimmigrant registered nurses under H-1A visas.

(c) Subparts F and G. Subparts F and G of this part set forth the process by which employers can file attestations with the Department of Labor for the purpose of employing alien crewmembers in longshore work under D-visas and enforcement provisions relating thereto.

(d) Subparts H and I of this part. Subpart H of this part sets forth the process by which employers can file labor condition applications (LCAs) with, and the requirements for obtaining approval from, the Department of Labor to temporarily employ the following three categories of nonimmigrants in the United States: (1) H-1B visas for temporary employment in specialty occupations or as fashion models of distinguished merit and ability; (2) H-1B1 visas for temporary employment in specialty occupations of nonimmigrant professionals from countries with which the United States has entered into certain agreements identified in section 214(g)(8)(A) of the INA; and (3) E-3 visas for nationals of the Commonwealth of Australia for temporary employment in specialty occupations. Subpart I of this part establishes the enforcement provisions that apply to the H-1B, H-1B1, and E-3 visa programs.

(e) Subparts J and K of this part. Subparts J and K of this part set forth the process by which employers can file attestations with the Department of Labor for the purpose of employing nonimmigrant alien students on F-visas in off-campus employment and enforcement provisions relating thereto.
