When legitimate couples run into problems at the interview it's not because of having anything to hide, it's usually because they failed to prepare carry for what they DON'T want to hide or forgot minor details about their relationship.
That's called the human factor where we all forget things.These IO's are not inhuman robots who do not know what real life is.They know and understand that life happens to everyone .
But for the most part we all remember details cause it is real and in memory.Which is the difference between a sham marriage and a real one . You can tell when when people are feeding you a line of nonsense or telling the truth .
I ask my wife my own siblings birthdays my moms b'day and i would have asked her straight out if the question came up in the interview.Cause i just do not keep track of these things never have never will. And as I mentioned earlier in this post we literally did not do any remmember these and that preparation whatsoever .
I brought a total of ten pictures from when the kids were born but the IO never asked to see anything no bills no statements nothing.
He asked when we bought the house and told him when and I told him straight out my names not on it for obvious reasons.And he said i understand completely.That point he told me to look at what he was doing which was stamping approved on my paperwork.
Asked if I have any questions and that he would put everything in as soon as we leave and I should have my GC in 2 weeks .I asked about the stamp in passport and he said they don't do that anymore cause it was being faked and they do GC faster now .
So do I tell everyone here to not prepare ?No you do what you feel comfortable with .cause it is your life your situation .Every situation will be a bit unique and require it's own direction.
But in the end a truly legitimate marriage will overcome any hurdles they throw at you.Some will go smoother than others cause that's life .
