Its so many questions... like MANY MANY MANY! They asked me to draw my room showing bed position ... what side of bed each of us sleep. Who wake up first... last movie we watched together... where.... last time we had sex... explain how was our first date... ask if my wife have any tattoo / scars and where, who pays the bills..... what we gave to each other for birthday / Christmas! Name of people who were at our wedding and engagement .... ( there is one blog you can find over 150 question there basically all questions that they asked) Yes I know its sounds scary! But remember just keep calm and tell the truth
After all questions, the officer interviewd my Wife and basically asked the same questions and them she called me to the room and said there is no more concerns and just wait for landing appointment.
And she explained about the interview request just because we have short time of relationship!
