If as PIC you bring someone none EU national from outside the UK into the UK who breaches immigration rules its I think £2000 a head fine to the PIC.
And each country is different with the rules. Just because your pax has a visa for the UK doesn't mean they are then legal for say France. But once they are into a schengin country they can pretty much go anywhere within the region because nobody else will check them.
