Worldwide Income - Proof of foreign income
I am a US citizen and my spouse came to the USA on a K-1 visa in early September, 2008. She has been living here ever since. For the 2008 tax year, we plan to file a joint tax return and make her a "Nonresident Alien Treated as a Resident" for tax purposes. To do that, we have to report her worldwide income she earned before she came to the USA.
My question is do we have to send some kind of proof of her foreign income she earned prior to her coming to the USA - similar to a W-2 form? In her country, they do not have such forms. Or do we just enter her income as part of the "Wages, salaries, tips, etc." without any supporting documentation? Thanks for any help you can give.
