A permanent labor certification issued by the Department of Labor (DOL) allows
an employer to hire a foreign worker to work permanently in the United States.
In most instances, before the U.S. employer can submit an immigration petition
to the Department of Homeland Security's U.S. Citizenship and Immigration
Services (USCIS), the employer must obtain an approved labor certification
request from the DOL's Employment and Training Administration (ETA). The
DOL must certify to the USCIS that there are no qualified U.S. workers able,
willing, qualified and available to accept the job at the prevailing wage
for that occupation in the area of intended employment and that employment
of the alien will not adversely affect the wages and working conditions
of similarly employed U.S. workers.
