You are a resident, for U.S. federal tax purposes, if you are a Lawful Permanent Resident of the United States at any time during the calendar year. This is known as the “green card” test.
You continue to have U.S. resident status, under this test, unless:
You voluntarily renounce and abandon this status in writing to the USCIS,
Your immigrant status is administratively terminated by the USCIS, or
Your immigrant status is judicially terminated by a U.S. federal court.
