Ok so...I heard from Eugenia about some of the details and now I'm confused!
We scanned our passports for both us and our witnesses, and sent her the paperwork for choosing restaurant, etc. She replied that we still need to send her our birth certificates, to "start the process of the single status certificate". Neither of us has been married/divorced before, so I'm not sure what this is for? None of the paperwork mentioned this previously, can anyone help me out?
