@amitabhbachan6 , Before I can answer this I need the following information ---1. Are you a US citizen/Resident/Resident for Tax purposes and if not a citizen/ Resident then you visa and country of citizenship; 2. Your spouse's citizenship -- I am assuming that she has a passport that was used for ITIN; 3. When did you marry and when did you get the ITIN issued ( really trying to know if the ITIN is still valid); 4. Spouse is a resident of which country -- you said she has no income and that you provide for her support.
Generally a non-resident alien spouse whom is a resident of one of the contiguous countries ( Canada and Mexico) can file jointly with a US citizen/Resident/Resident for tax purposes. There is a special exception also for India under some circumstances. Hence all the above questions
