If I will apply for a tourist visa to a country that requires a good?
they will know it if your country gives it to them. Some do; others don't. The UK has long had a practice of issuing duplicate passports to people travelling to, for example, Israel and surrounding hostile Arab states. I kinda wish they would do the same for their own border too: I have Chinese visas in my current passport and this produces what we call a kerfuffle at the UK border even though given mynpassport number their computers list all my travelling anyway.
