On the w-7form I can put down letter E... my wife is a US citizen. It requests that you send a valid passport that shows the visa entry date. I did not come to this country with a visa so there is no entry in my passport. How can I get a ITIN so we can file joint taxes. Thank you for your help.

A U.S. citizen or resident, can file joint return as residents even when the foreign alien spouse has never been to the U.S. Attach W-7 (ITIN application) with the tax return. http://taxipay.blogspot.com/2008/02/filing-status-for-married.html
