Choice 1: File non-resident tax return. You can deduct moving expenses if not reimbursed.

Choice 2: You can file resident tax return as Married Filing Jointly.
You will get standard deduction of $11,400 and exemptions ($3,650 each) for both of you.

You must both declare your worldwide income for 2009. If you have any foreign income, and on that income you paid taxes in the foreign country, then you can claim foreign tax credit (Form 1116) or you can use Foreign Earned Income Exclusion (Form 2555).

You will complete forms W7 (application for ITIN) for your spouse and attach with your tax return. You can also deduct moving expenses. Your U.S. Tax Return: The U.S. Visas
