Dave McElfatrick denied a Visa to the USA

Dave McElfatrick, late of Coleraine and I believe based in Belfast these days, is one of four cartoonists, and the only non-American one, who produce the cynical stickman webcomic Cyanide and Happiness. He wants to go to America to work on some animated shorts with his co-creators - but they won't give him a Visa, apparently because they don't think he's an important enough artist. There's a petition set up, so if you want Dave to go to America, go and sign it!
