If she is a nonresident, you both will need to sign an election to file married filing jointly declaring your worldwide income. Otherwise you will need to file a married filing separately 1040 and she will need to file a nonresident 1040NR as married filing separately.
If, at the end of your tax year, you are married and one spouse is a U.S. citizen or a resident alien and the other spouse is a nonresident alien, you can choose to treat the nonresident spouse as a U.S. resident.
To make this choice:
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.
You will need to attach this statement to your printed TurboTax return and mail to the tax authorities. You cannot e-file your return.
Please see page 8 in Publication 519 for more information.
If you paid for care for your child, dependent, or disabled spouse while you worked or went to school, you may get a nice tax break - This is under Child and Dependent Care Credit.
