The interview was definitely easy. We were just asked for a general timeline of our relationship. I lived with my husband in Turkey for nearly two years, and the officer was definitely interested in that. She was asking a lot of geographic questions, but in a way that I wasn't sure if it was because were were telling her which places to visit when she goes, or because she wanted to make sure we both knew which cities we were recommending. My memory wasn't so great in this part. She asked how far away we lived from Ankara, the capital of Turkey and I would say, "Two hours by bus?" but my husband would answer, "No. Six hours by bus."
I think it definitely helped that we gave our cats flea baths the day before and when we told the officer, we both showed her the cat scratches on our arms at exactly the same time. Pretty hard to fake that!
Probably the hardest was when she asked about our future plans. Do you want any children? Are you going to travel together? What are you going to be doing in the next few years? My husband and I shrugged, and said we were going to Washington for Thanksgiving.
She was really sweet. She would go into tangents about her own husband and life, and then say, "So that's me! But... we're here to talk about you, huh?" She was the same officer that interviewed the prior couple that ended up having a stokes interview, however, so maybe it's case by case dependent.
Good luck with your process! I hope you get an interview date soon. Yes, we'll be filing the N400 as soon as we can so maybe I'll see you in that thread next year, too!
