There is a quesion in our N-400 form about trips which we take outside of the U.S. I mentioned all trips where I went and when,I didn't have any problems with it becase I knew about this requirement long time ago and kept track of it. Last night I went through my form and passport stamps and realize I don't have any stamp about my trip to the carribeans on the cruise. Does the IO usually go throagh the passport to see every stamp or they don't do it?
