Certificate to certify non-availability birth certificate

[gplkrr]

Hello all-
I am planning to apply concurrently for I140 and I485.
I do not have my birth certificate and I understand I need to get an affidavit from my parents and a non-availability certificate.
Can some please advise:
1. what exactly does the birth certificate affidavit need to say? I someone can attach the language text, I would appreciate it.
2. How is this affidavit executed.
3. what exactly does the non-availability need to say? I someone can attach the language text, I would appreciate it.
4. How is this certificate executed? Who issues it and does it have to be from the place of birth?

Would appreciate e if you could share any dos/don'ts related to this step.
Thanks
Its_me

See immihelp.com and other immigration sites which have the model letters.
Affidavits have to be given by adult relatives preferably who may not benefit from your immigration. Each country has a different standard. Generally it is the local judicial paper (stamp paper in India)
No availability letter should be received from the local authority of your place of birth. If you are not able to get one, you can get a proof of birth from your country's embassy in washington.
