I am a F1 status student. and I came to US to start my study in 2012. I understand that I am a non-resident alien for my first 5 years, so 2016 is my fifth year. The thing I don't understand is this year, 2017, is the sixth year, but I am filing tax for 2016, which is my fifth year. Thus for filing 2016's tax, am I a resident alien or non-resident alien?
