u can file joint tax return for 2008 of u married in 2008.

you can choose to treat the nonresident spouse as a U.S. resident in this situation. If you make this choice, you and your spouse are treated as residents for your entire tax year for the purpose of your federal individual income tax return, and for the purpose of withholding U.S. federal income tax from your wages.

Generally, neither you nor your spouse can claim tax treaty benefits as a resident of a foreign country for a tax year for which the choice is in effect and you are both taxed on worldwide income. However, the exception to the saving clause of a particular tax treaty might allow a resident alien to claim a tax treaty benefit on certain specified income. You must file a joint income tax return for the year you make the choice, but you and your spouse can file joint or separate returns in later years.

Attach a statement, signed by both spouses, to your joint return for the first tax year for which the choice applies. It should contain the following information:

A declaration that one spouse was a nonresident alien and the other spouse a U.S. citizen or resident alien on the last day of your tax year, and that you choose to be treated as U.S. residents for the entire tax year
The name, address, and identification number of each spouse. (If one spouse died, include the name and address of the person making the choice for the deceased spouse.)
