PD Feb-22
Interviewed this week- Baltimore field office.
We were ask for our ids, sworn in, ask for passports. They Ask my USC husband my full name, date of birth, where I was born, our wedding date and who attended. If he met my parents, when, where. A detailed description of how our relationship started. They ask him to detailed our first date. We were in a long distance relationship bcz I lived in ny n he in md. He was asked how we maintained the relationship. They asked him my parents name and where they reside. They asked for joint documents. We only have a bank account together. Then the questions was directed to me. I was ask his full name, date of birth, how we met, who introduced us, when did I move in, who proposed, if I anticipated his proposal or if I was shocked, about his parents name and where they reside, detail spelling and date of birth of his sons name. Hw often I see my stepson, what my husband do for fun, then he was asked what I do for fun. Then they asked me where he works and his post at both jobs. And other questions I can't really remember. The interview lasted about an hour, we weren't separated and our IO was stern but for the most part the interview was casual. I believe we were drilled because of our 20 yrs age differences. And at the end he read the yes no questions and ask me about my last job abroad and he said I'll approve your case but unfortunately the background check isn't completed. He explained hw to remove conditions and to expect approval letter in the male should the background check b good and he recommend applying for citizenship in 3 years. So i guess it's just waiting.
