I visited India in April this year and did a court marriage (got the marriage certificate). The traditional marriage is in Dec 22. My wife’s interview is scheduled for the first week of October. What documents would be necessary to prove legitimacy of marriage? As of now, we have photographs at the court with the family, exchange of rings, a few time-stamped photos highlighting our relationship (10 years) and the marriage invitation card for the traditional wedding. Are these sufficient?
