Deductions & credits

Follow up... I plan on getting her an ITIN number.  I am SOFA member living abroad on orders.  I know the ITIN number can take a minute, but I should have it in time before filing.  My spouse worked, I read I have to claim her income too, but she pays taxes to her home country.  Would I still claim her income on my return, even though there is no W2 for her?  How would I enter that data?
