When a foreign national applies for adjustment of status based on marriage, he/she must prove to USCIS that the marital union is “bona fide.”
This means that the couple got married because of love—not solely due to obtaining legal permanent residency.
Applicants must provide certain documents that demonstrate proof of bona fide marriage to USCIS officials to avoid being accused of green card fraud.
These documents are attached to the petition itself or when the scheduled green card interview takes place.
