I don't understand what the first question your asking means... but as to the second question:  He left, as far as I know, firstly, because it was easier to get funding for his films in England.  Secondly, he became a bit of a recluse because of some death threats he received after Clockwork Orange (but so did Scorsese after Taxi Driver, and he didn't leave the country)... Plus, from stories and interviews I've read, Kubrick sounded like a naturaly paranoid man.
