Hi FiveStar,
1. Do you have anyone in the neighbourhood, who is elder to your parent, who can give a affidavit ?
2. More importantly, you need a letter from Municpal Corporation, that they did not issue Birth Certificates at that time (it is calledNON availability certificate or something like that). Basically they give a letter stating that your parents birth was NOT RECORDED.
My friend who was in the same case as yours, had to get this letter in order for them to proceed the case further.
Hope this helps.
Btw, did you submit I-130 and 485 together? If so, can you please let me know two things.
1. Mailing address of USCIS to post these forms together.
2. Which check box did you submit? I am specifially talking about Part2 (Application Type) from Form I-485. Which check boz should I select here? If A, then I dont have any copy of any approval notice.
