Claiming dependent from other country for fed tax
So I've been living in the states for an year now and I need to file my taxes. I want to know can I claim my parents (not living in US) as dependents? They do not have a SSN (since they have never come here) and they are retired.
Searching a bit i've found I can get an ITIN by giving form W-7 and claim them as dependent. Am I reading this right? How much time does it take to get an ITIN after submitting the W-7 if anybody knows?
