I just got married to a US citizen just want to ask what and what form i need to fill to file for change of status. Came in with a B1B2 visa

You and your spouse will each need to file forms. Your spouse will need to complete Forms I-130, G-325A, and I-864. You will need to complete Forms I-485 and G-325A. You will also want to complete Forms I-765 and I-131 if you would like employment authorization and advance parole. These Forms must be properly completed and filed with the appropriate fees and supporting documentation.
