I went through the K1 visa process. We applied in May and had the visa in hand by September and the green card by February. The process goes quick as long as your not from a “high fraud country”, your relationship seems legit, and you can actually fill out papers correctly. Their timeline is more than likely accurate, but they probably knew each other no more than a few months or weeks before he proposed.
They’re relationship seems very strange to me like almost hypocritical.. we’re both innocent virgins but we met because he was constantly hitting on me through my bikini pics that I post for the world to see.. I’ve been to Spain many times and I felt uncomfortable at the beach because I was wearing a top and everyone else was topless, they’re very sexually open and with that I find it extremely hard to believe that this 26 year old man is a virgin.. lol and that’s probably why we know nothing about him.
