I plan to apply for my parents after they come to US on visitor Visa. I know they will need birth Cert & Marriage Cert. What are the other documents I need them to bring to US? How many original affidavits of Birth are required?
All the required documents are on the I-130 and I-485 app instructions. I suggest you complete the applications in draft before they arrive, so they can get any documentation that is missing. In particular, the I-485 asks very detailed background questions (your parent's academic, employment, and social history) so it's best if they complete it at home so they have all their records present.
You only need copies of everything for the app, but USCIS reserves the right to ask for originals later, so you should have them available. It appears that they always RFE for original Affidavit of Birth forms from parents from India so it could save time if you sent originals of those initially.
I will be applying for Mother as well as father. Do I need to send my original birth cert with the application? Do I send my original birth cert with my fathers application or mothers application? One of the application will have a copy of my birth cert, is that ok?
Per above, original birth certs are not initially required and per postings here, USCIS does not later RFE for them.
