Labor Certification is one of the most popular employment-based methods for obtaining permanent residency in the United States. A Labor Certification is a determination made by the Department of Labor certifying that there are no U.S. workers able, willing, qualified, and available for the position offered and that the employment of a foreign national will not adversely affect the work conditions of U.S. workers. The Program Electronic Review Management (PERM) System replaced the labor certification procedure that had been in place for many years. Applications under the PERM system are electronically filed and are adjudicated in a more rapid fashion. The US employer may submit an immigration petition to the U.S. Citizenship and Immigration Services (USCIS) for an alien worker only after an approved labor certification is received from the Department of Labor.
