Netisan:
The best way for you to file is to wait until June 2006, then file as a resident alien under First Year Choice. You hsould download Form W-7 from
www.irs.gov, fill it out, have your wife sign it and attach it to your Form 1040, 1040A or 1040EZ, along with a notarized copy of your wife's passport.
Filing jointly as a resident alien will allow you to claim a $10,000 standard deduction and $6,400 in personal exemptions. It will cause you to effectively forfeit any refund of withheld Social Security or Medicare taxes during your F-1 visa status, but if no Social Security or Medicare taxes were withheld, you will NOT have to pay these taxes after the fact.
