Yes. I applied to have the cased moved to NVC. Took a few months and something -very- interesting happened.
NVC asked for marriage certificate for my parents. We were able to get a marriage certificate from the church where they got married. Submitted that document.
NVC soon approved my mother's application. But not my father's, despite us submitting exactly same documents. NVC said the marriage certificate we submitted was not in compliance with their 'accepted' list of documents.
We resubmitted the same marriage certificate for my dad while also looking into obtaining a civil document. Our parent's marriage was not recorded with the government back in the day, so we knew it would be an uphill battle.
While we were working on/ waiting for the civil marriage certificate, we got another notification from NVC (a few months after resubmitting the church issued marriage certificate for my dad) informing us his case was approved. 🤷♂️
Considering both applications are now approved, we decided not to submit the civil marriage certificate at this point. It has been a few months since both applications were approved. Now we are waiting to hear from the embassy regarding interview for them.
