Fair point, I accept it depends where you are.
I certainly know of one major airport where a few captains have been hauled over the coals because passengers had not complied with a required immigration process (funnily enough international passengers ending up on a domestic gate, yes, a ground handling stuff up, but the P1's got it in the neck..."because they should have known") so I'm very wary of using the "it's nothing to do with us, we're only pilots" line of defence....at the very least I make sure I'm on record
as having tried to make sure things were done properly...
