Oh the poor drink drivers.... what a shame. There seems to be far too much mollycoddling nowadays.
As a foreign citizen you have no right to go to America or any other country, generally they want you because you bring money.
As far as I'm concerned it's the sign of a bad or feeble person. Personally I wouldn't want drink drivers coming over here from America so why should British drink drivers go over there.
Drink drivers kill people with their stupidity and selfishness, they deserve nothing but derision, in some companies you can't get a job with a DD conviction no matter how long ago so why would any country want them?
