1. I was still a non-resident in tax year of 2005, but my wife changed her status to resident (because she has been here in the US for 5 years since Aug.05) Can we file Joint Return? Somebody told me only citizen or permanent resident can file joint return with their spouses.
2. My wife has been worked on OPT during Mar-Dec 2005, but she chanaged her status to resident on Aug-05, should she file as Dual-status or Resident? Which form she should choose? 1040 NR or 1040?
Thanks a lot for your assistance.
