You can use your Green Card to:
- Prove employment eligibility in the United States when completing the Form I-9, Employment Eligibility Verification.
- Apply for a Social Security Card and a state issued driver’s 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.
