Hey @Ana.M- thank you!
I stand corrected, my mom said they asked for all of the originals of birth /marriage/death certificates, spravki o ne sodimosti (we had two from two different countries), translations of everything ( I did have them notarized and certified per the website guidance).
Questions were: how did I get to the US? Where would she be living? And then said her visa was approved.
Mom said there were lot of people that were not getting approved as they were missing one or more docs.
I am sure everything will go well for you guys next week! Good luck! Please post an update, keeping fingers crossed for you!
