1 - what happens if I don't bring my passport to the interview? I now know
that some of the exit dates on the application that I filled are not
correct
2 - what can the INS do to me if they find out that there are
discrepancies between my application and my passport? what happens if I
just bring a new passport to the interview?
3 - do they have the records of my entries/exits in their system? I
mean do they need my passport to verify this info or do they have it
in their computer system?
4 - since I filled the application I was out of the country most of
the time - how do they view this?

thanks
