RFE for birth certificate

[sea_gc]

I have filed a GC application for my parents as of Jan 2006 - They are currently in the US and have applied for I-485. They did their finger printing last month. Recently, we received a RFE for the birth certificate. I had submitted a copy of the affidavits in the application (2 for each parent). I had not submitted a non-availabilty of birth certificate earlier.

Question:
My father was born pre-independence in a city which is now in Pakistan. His Indian passport says that he was born in Pakistan. Hence, all the GC forms say that he was born in Pak. Now, it is not possible for us to get a non-availability of birth certificate from the municipal authority in Pak.
I am sure there have been many cases like these in the past. However, I was unable to get any concrete information from BCIS.
The first agent I talked to insisted that I get a letter from Pakistan.
Today, another agent did not insist that a letter was necessary but did not commit that it wasn't needed. She focused on secondary evidence.

My current plan is to -
1. Send a copy of the affidavits again (I asked thee agent and she said a copy is fine)
2. Send a notarized copy of the school certificate showing the name and date of birth. Since this is in Hindi, I'll be translating it and notarizing it as well.
3. Send a letter saying that it is not possible to obtain a letter from the municipal authority.

Is this sufficient for BCIS? What else should I be doing?

Thanks.


I had previously posted this the I-485 forum but did not get any response there. I would appreciate any insight.

I am not sure. This India-Pakistan would be the case for many people. If someone has done this successfully, please post the experience as it would be very useful to many.
