I was refused entry into Pakistan due to a technical issue (incorrect mode of transport declared on visa application form - they are really strict about that) and I was asked to come back using the mode of transport indicated on the form. I never went back, but I did have a CANCELLED stamp on my passport.
I have since gotten a new passport, and intend to visit a non-FCC country. Do I have to declare this incident as a "denial of entry"? Can they ever find out about it if it's not on my passport? Put another way, is such information shared between non-FCC countries? Additional info: I have since then travelled 8-10 times and never once been asked about it while exiting India or entering any other country (none of them FCC countries).
