My wife is having her Follow on to join Immigration visa interview ('Follow on to Join') in April 2004. I am in the processing of collecting the documents for my wife's interview. We got married on Friday Feb 15/2002. We wanted to register the marriage on Monday 18th as the register office is closed on Saturdays and Sundays. We were not able to register our marriage on 18th as I left within 2days to US leaving my wife behind, due to work emergencies. I went to India n in May 2002 to register my marriage and to apply for the H4 for my wife. Before I could apply for the H4 my adjustment of status got approved and I was advised by the consulate to apply for the follow on to join instead. The question I have is, For my wife's interview this April, the marriage certificate that I got issued 3 months after the marriage is still good or do I need some additional documents to validate the marriage certificate.
