I think the only way to get this done is get a marriage certificate from India. But I can't ben 100% sure. Check with someone - either email/Twitter DM the consulate or check with BLS to see if there is a work around.i am trying to apply OCI for me(Adult application) but it requires marriage certificate and we recently got married and didn't got chance to visit india and apply marriage certificate. Any advise how i should approach this situation?
This is why, if you are residing abroad, it is prudent to get the marriage certificate ASAP after the marriage to avoid these problems.
