How to Verify a Green Card

People who immigrate to the United States as a permanent resident alien are issued an identification card called a Green Card. The Green Card is proof that a person may live and work anywhere in the USA. Green Cards are used as proof of an immigrant's eligibility to work in the USA, so it may be necessary to verify the status of a Green Card. An individual or employer can verify green cards using the United States Citizenship and Immigration Service website E-Verify online service. The E-Verify system compares information from the Department of Homeland Security and the Social Security Administration to confirm employment eligibility.

Navigate to the United States Citizenship and Immigration Service (USCIS) website at Click on the link "Information for Employers and Employees." Click on the "E-Verify" link in the right frame. Log into your employer account or enroll in USCIS E-Verify.

Create a new case after submission of form I-9, which is the Employment Eligibility Verification form. Answer each question about the employee including birth date, Social Security number and USCIS number from the Green Card. Enter the expiration date, if required.

Wait for the USCIS system to search the databases for the required information. Close the case if E-Verify reports "Employment Authorized."

Log out and return in 24 to 72 hours to check the status of the case verification if the system returns a "Tentative Nonconfirmation" message. Close the case when the USCIS returns a final determination of the employment eligibility status of the person named on the Green Card.


  • E-Verify uses information that is supplied by the Form I-9 supplied by employers. Complete and return all employee I-9 forms within three days of employment.

    Close a case and open a new case if the "tentative nonconfirmation" message is a result of typographical errors.


  • Always verify each entry into the E-Verify system. Inaccurate information or typographical errors will result in incorrect results of a "tentative nonconfirmation" response.

    Always close a case after confirmation of Green Card status is received.
