Labor Certification

Requirement for U.S. employers seeking to employ certain persons whose immigration to the United States is based on job skills or nonimmigrant temporary workers coming to perform services for which qualified authorized workers are unavailable in the United States. Labor certification is issued by the Secretary of Labor and contains attestations by U.S. employers as to the numbers of U.S. workers available to undertake the employment sought by an applicant, and the effect of the alien’s employment on the wages and working conditions of U.S. workers similarly employed. Determination of labor availability in the United States is made at the time of a visa application and at the location where the applicant wishes to work.
