Green Card and Substantial Presence Test
Green Card Test
You are a Lawful Permanent Resident of the United States, at any time, if you have been given the privilege, according to the immigration laws, of residing permanently in the United States as an immigrant. You generally have this status if the U.S. Citizenship and Immigration Service (USCIS) issued you an alien registration card, Form I-551, also known as a “green card.” You continue to have resident status, under this test, unless you voluntarily renounce and abandon this status in writing to the USCIS, or your immigrant status is administratively terminated by the USCIS, or your immigrant status is judicially terminated by a U.S. federal court.
