Hi all,
I and my wife are Ph.D. students. My wife stayed more than 5 years in US that makes her resident alien I think. I am non-resident. Can we file jointly as resident? Which form should we use?
Yes, you can file jointly if EITHER of you meet the residency test.
You will probably file Form 1040EZ, but you need to attach a statement to the return that YOU choose to be treated as a resident alien for all of 2010.
