As a U.S. permanent resident, how to apply for a Green Card for my family member?
To obtain a Green Card for your family members (spouse and children), you must file Form I-130, Petition for Alien Relative, provide proof of your status to demonstrate that you are a permanent resident, and submit evidence of the qualifying relationship such as a birth certificate, marriage certificate, divorce decree, etc, including proof of any legal name change for you or your family member (the beneficiary).
