Green Card (1990)

Urban horticulturalist Brontë Mitchell has her eye on a gorgeous apartment, but the building's board will rent it only to a married couple. Georges Fauré, a waiter from France whose visa is expiring, needs to marry an American woman to stay in the country. Their marriage of convenience turns into a burden when they must live together to allay the suspicions of the immigration service, as the polar opposites grate on each other's nerves.
