H4 visa scheduling appointment without marriage certificate

Hello,Since there is a wait time of 2-3 months going on now, my fiance and myself are planning to schedule an appointment now for h4 visa interview so that we can get the slots and travel back together. Currently we are unmarried but will be married based on the day of visa interview and have the marriage certificate. Can we go ahead and schedule an appointment now so that we can get the visa interview slots or do we need to get married first to schedule the interview and book the visa appointment??It’s urgent and any help would be appreciated

Yes, you can do that. Complete the DS form as married and appear for interview later. If asked about it, you can say that b/c the dates were backlogged, you applied in advance and selected dates when you knew you would be married.
