No. The labor certification is job specific, location specific, and employer specific and essentially confirms that the specific U.S. employer who filed the application with the DOL was unable to find a U.S. worker to fill the position. The labor certification also verifies conditions of employment such as the wage level and minimum job requirements. These are conditions that tend to change from employer to employer and from job to job. As such the labor certification is only useful for the U.S. employer who actually filed the application with the DOL unless a subsequent employer is a successor-in-interest.
