| Based on marriage date, I can fill jointly, isn't? ---- Yes, based on your marriage date you can file jointly.
How about based on the date of her arrival? I run a residency test on her as she was an F-1 student, got an OPT but had to leave in 2006 (Thus, she already has SSN). The result is she is non-resident. ---- She will be treated as a resident of the U.S. for the entire 2007 year if you make the election to file jointly.
On one post I read that as long I am considered as resident my wife will be too if we file jointly and the physical presence is irrelevant for tax purposes. Is this true? ---- Yes.
If we can file jointly, is there any paperwork regarding our marriage to attach with our form? ---- You do not need to attach anything to prove that you are married. However, you do need to make a section 6013(g) election to file jointly that will need to be attached to your tax return. |
