What Documents Are Needed for a PERM Labor Certification?

March 31, 2026

For many employers and foreign workers, the path to an employment-based green card begins with a single, critical step: the PERM Labor Certification. It is often the most complex and time-consuming part of the process, yet it is absolutely essential. The Department of Labor (DOL) uses this certification to verify that there are no qualified U.S. workers available for the position and that hiring a foreign national won’t adversely affect U.S. wages.

At Zaveri Law Firm P.C., we understand that the volume of paperwork required can feel overwhelming. Missing a single document or misplacing a record can lead to delays or denials. To help you navigate this, we have broken down exactly what documentation is needed to build a strong, audit-proof case.

Documents Required from the Employer

The burden of proof in the PERM process falls heavily on the employer. You must demonstrate that you have made a good-faith effort to recruit U.S. workers and that the job offer is legitimate.

Key Employer Documentation:

• Prevailing Wage Determination (PWD): A formal document from the DOL stating the minimum wage that must be paid for the position in your specific geographic area.
• Job Description: A detailed breakdown of duties, minimum education, and experience requirements. This must be consistent across all recruitment channels.
• Recruitment Report: A signed summary detailing the recruitment steps taken, the number of applicants, and lawful, job-related reasons for rejecting U.S. candidates.
• Proof of Advertisements:
  • Sunday Newspaper Ads: Copies of tear sheets or electronic tear sheets from two consecutive Sundays in a newspaper of general circulation.
  • State Workforce Agency (SWA) Job Order: Proof that the job order was open for at least 30 days.
  • Internal Notice of Filing (NOF): Evidence that the job opening was posted at the worksite for at least 10 consecutive business days.
  • Additional Recruitment Steps (for professional roles): Evidence of at least three additional recruitment methods, such as detailed printouts from job search websites, an employer’s website, or trade journals.

Documents Required from the Foreign National

While the employer drives the recruitment, the foreign national (the beneficiary) must prove they were qualified for the role before they were hired.

Key Beneficiary Documentation:

• Educational Credentials: Copies of all degrees, diplomas, and transcripts. If the degree is from outside the U.S., a formal foreign credential evaluation is usually required.
• Experience Letters: This is a common pain point. You need sworn affidavits or letters from previous employers on company letterhead. These letters must explicitly state:
  • Job title
  • Start and end dates
  • Whether the job was full-time
  • A detailed list of duties performed (matching the requirements in the PERM application)
• Skill Certifications: Copies of any relevant professional licenses or technical certifications required for the role.

The Importance of the Audit File

One of the most frequent errors we see is employers failing to retain physical proof of their recruitment efforts. Even if your PERM is approved instantly, the DOL can audit you.

You are required by law to maintain a “PERM Audit File” for five years from the date of filing. This file must contain every document listed above, plus the signed PERM application (ETA Form 9089). If you cannot produce this file during an audit, the certification can be revoked.
