My husband came to USA on a K1 visa and we were married in California, USA. I want to apply for my OCI since we have been married for 2 years and it says "apostilled marriage certificate" required. Does that mean I get it apostilled here in California for India? I was also reading about the Apostille Convention and am a little confused, does it mean it's required to apostille it but it's still valid in all the other countries part of the convention?
