You can use your Green Card to: 1  Prove employment eligibility in the United States when completing the Form I-9, Employment Eligibility Verification. 2  Apply for a Social Security Card and a state issued driverâs license. A Green Card is valid for readmission to the United States after a trip abroad if you do not leave for longer than 1 year. If your trip will last longer than 1 year, a reentry permit is needed.
