1) Can I still claim them as dependents for tax deduction for 2006?
2) Can I still apply a ITIN for them even they are not in US?
3) I don't have any materials for their information, such as passport and visa. The IRS website says a notarized copy of passport is fine. Is a notarized copy in China fine since they are in China now?
4) Any other materials should be notarized, such as, I-94, passport, visa, or air tickets? or anything else?
Many thanks.
