The other thread sparks my interest in this topic. I am a British citizen but want to learn more about trading at those prop firms in America. Is it possible for me to go there to trade one or two months without a VISA (or with a tourist visa). As far as I know, a British passport holder should be able to stay at US for 90 days without a tourist VISA. I have no intention to stay at the USA so I don't want to apply for a working visa. Thank for any comment.
