Tax Return

[akh]

Hello everyone,

I have a question about tax return forms. I had F1 visa since 01/01/2016 until 03/24/2016. I applied for Adjustment of Status and EAD. My EAD application was approved on August 2016. Also, AOS application was approved on 02/21/2017.
I do not know how to fill up the tax return form. Do I need to fill resident or nonresident forms?
Thanks for your help.

You were non-resident for tax purposes during the time you were in status on your F-1 visa
You were a resident for tax purposes afterwards
You were a part-year non-resident and part-year resident for tax purposes

If you were married to a US citizen on the last day of 2016, you can elect to file Married Filing Jointly with your spouse.
