A marriage immigration green card allows a foreign spouse to obtain green card status through marriage to a U.S. citizen or permanent resident. Applicants need to submit relevant marriage certificates, evidence of living together, and other supporting documents. Applicants also need to go through processes such as interviews and surveys to demonstrate that their relationship meets statutory requirements. During the application process, applicants may be required to provide personal background information, medical examinations, and financial support documents, among other things. Once approved, the applicant can obtain a temporary green card.
