In brief, the PERM process requires the petitioning employer to conduct a series of recruitment activities to test the labor market before filing the application. If sufficient able, qualified, and willing applicants (U.S. citizen or Permanent Resident) are not found for a position through the recruitment process, the employer can submit a PERM labor certification application. Once it is certified, the employer files I-140 petition which demonstrates an offer of a permanent job. After than, depending on the priority dates of employee’s country of origin, a green card can be obtained.
