I got married in 1992 and for some reasons never got my marraige certificate.

Recently, I got a Marraige certificate from the Indian Consulate in Chicago. Is this sufficient for consular processing?

Can I get an affidavit for the same. Any suggested formats??

If I have to take a Marraige Certificate from the Vijaywada, A.P, How long will it take and what is the process?

Please respond ASAP as my CP is scheduled for March

Thanks
Srini
