I am a naturalized US Citizen looking at filing a Green card for my parents who are currently in the US on visitor(B2) visa. My questions are:
1. Is there any option for premium processing for applying for Green card for parents?
2.Can I file Green card (I-130) and Adjustment of status (I-485) simultaneously for them even if they are here on B2 visa?
i) If so, how long does it generally take for requests for finger printing, request for immunization and Interview (if needed) to come in respectively?
ii) What is the approx time for the I-130/I-485 to be approved?
iii) How long does it take for the Advance Parole (I-131) document to be received once I apply for I-130/I-485 together so they can travel to India if needed? If they have to travel to India before the advance parole document comes through, can they come back on B2 visa without affecting their application?
iv) Can they legally apply for SSN based on I-130 and I-485 being filed so they need to wait for approval?
v) Can they legally get Insurance based on the pending application?
3.If they instead go back to India and I only file for I-130 right now, approx how long is the entire consular processing taking these days?
4.For documentation,
i) Are birth certificates of parents required? If yes, they don't have birth certificates, are too old for the certificates to be actually available and there are no elder relatives still alive to give an affidavit, what options do I have to get affidavits done either in the US or in India?
ii) For my father, he doesn't have a marriage certificate. What options do I have to get an affidavit done either in the US or in India?
