My first experience at the Lagos embassy ended in a sort of anti climax because all I and my fiancee had researched about K1 visas seemed to be myths. As per the basic show evidence of relationship, which I did, I answered too many questions, some routine, some mind boggling. To be candid, the CO wasn't rude but she didn't betray any emotions either. I've been called back for a second interview and reading so many conflicting reports from the forums just makes me want to get all this over with.
