You may be eligible for AOS to become a lawful permanent resident. One of the requirements is that you have a family member that can petition for you. Your U.S. citizen child who is over 21 can do this. You must prove this is your child or stepchild either by providing a copy of your child’s birth certificate showing you as the parent or adoption papers or by a marriage certificate indicating marriage to the child’s biological mother or father.
The second requirement is that you have entered the U.S. legally. That usually means you entered with either a visa or a border crossing card. You must provide a copy of either as proof. It is okay if the visa or border crossing card has expired. You are also able to apply for a work permit to get permission to work while you wait for your application to be processed.
Here is a general roadmap of what to expect. 1. Apply for adjustment of status. 2. Attend a fingerprint appointment, which is called a biometrics appointment. USCIS will schedule a time for this usually at the local USCIS office. 3. Attend an interview with a USCIS officer at an office in the United States to review your application. Your Adjustment of Status attorney will help you prepare for this interview. 4. Wait for a decision.
If approved, you will be notified, and you will be able to receive your permanent resident card.
