GovAssist’s team is here to support your journey, whether you’re an employer, skilled worker, or advanced degree professional.

What Is PERM Labor Certification?

PERM (Program Electronic Review Management) is the standard process for most employment-based green card applicants in the U.S. It requires employers to prove there are no qualified U.S. workers available for the job before sponsoring a foreign employee for permanent residency.

Key Features of PERM

Employer sponsorship required
The employer must initiate and pay for the process.
Labor market test
Employers must advertise the job and show no qualified U.S. worker is available.
Prevailing wage
The job must pay at least the DOL-determined prevailing wage for the position and location.
Three-step process
1. PERM labor certification (DOL)
2. I-140 immigrant petition (USCIS)
3. Adjustment of status or consular processing (green card)
No self-petitioning
Employees cannot sponsor themselves.

Who Typically Uses PERM?

Professionals in STEM, business, education, healthcare, and more
Workers whose employers are willing to sponsor and complete the recruitment process
Positions not eligible for special waivers or national interest exceptions

What Is the National Interest Waiver (NIW)?

The National Interest Waiver (NIW) is a unique green card path for advanced degree holders and individuals with exceptional ability. It allows applicants to bypass the PERM process if they can show their work benefits the United States as a whole.

You can self-petition—no job offer needed.
No labor market test
No need to advertise your position or prove the lack of U.S. workers.

Scientists, researchers, entrepreneurs, healthcare professionals, and other experts
Individuals making significant contributions to U.S. society, economy, health, or culture

PERM vs. NIW: Step-by-Step Process

PERM Process

Employer requests wage from the Department of Labor (DOL).
Recruitment & Labor Market Test
Employer advertises the job and documents all recruitment steps.
PERM Application (Form ETA 9089)
Employer submits to DOL for certification.
I-140 Petition
After PERM approval, the employer files I-140 with USCIS.
Adjustment of Status or Consular Processing
Employee applies for a green card if a visa number is available.

File I-140 Immigrant Petition
