You will have to file your taxes as a non-resident if you do not meet the green card test or the substantial presence test.
You are a resident alien of the United States for tax purposes if you meet either the green card test or the substantial presence test for the calendar year (January 1-December 31).
If you meet the green card test at any time during the calendar year, but do not meet the substantial presence test for that year, your residency starting date is the first day on which you are present in the United States as a Lawful Permanent Resident. However, an alien who has been present in the United States at any time during a calendar year as a Lawful Permanent Resident may choose to be treated as a resident alien for the entire calendar year.
