F1 student filing as resident-alien, questions on what forms to file
Hi,
I started my undergraduate study in USA from 1998 to 2002 as a F-1 student.
I came back to the school to start the graduate school in December, 2006.
For the year of 2007, I did not earn anything other than bank interests.
However, school encourages me to still file the tax form even if earning is zero dollars.
My questions are as follows,
1) I am considered as Resident-Alien instead of Non-Resident Alien. So, I would like to know what forms I should file.
2) I am married, but my wife is F-2 and does not have social security number. I can still file the tax return as joint or it has to be single ?
3) Any issues to be careful about ? What if I don't file the tax form at all since I did not earn anything other than bank interests ?
I am most curious about number one question and I am seeking help.
Thank you
