@user17597544422 thank you for your reply. I suspected that ( i.e. CAA ). Now I understand why she received the letter from the ITIN processing center. So yes send in the response. However, I would not ask for her to be treated as a resident because this may expose her world income to US taxation. Part of the issue is that generally a dependent visa confers the same tax status to the holder as that of the primary visa holder-- the question being what is her start date ? Is it the date of admission of the dependent or that of the primary visa holder ? By asking her to be treated as a resident for the entire year, you would be taking a stand that her world income for the entire calendar year -- the benefit being the ability to use standard deduction. But as you said you have already filed the return MFJ -- so this whole thing may be moot.
Is there more I can do for you ?
