What are the requirements and process for getting married to a green card holder in the United States?

To marry a green card holder in the United States, you must first obtain a marriage license from the local government. Both parties must be present and provide identification. After getting married, the green card holder can petition for their spouse to obtain a green card through a process called adjustment of status. This involves submitting various forms, supporting documents, and attending an interview with U.S. Citizenship and Immigration Services (USCIS). The process can be complex and may require the assistance of an immigration attorney.
