I'm a London based short-end bond trader. Am seriously thinking about doing a stint in California around the Orange County/San Diego area. None of the London based firms have offices in California, only chicago and new york. Does anyone know any prop firms that either allow you to put your own money down or back you? And do they work they same way as firms in London do, i.e., a monthly desk fee and spin costs and the trader takes about 80% of the profits at the end of each month. I've heard about the firm Bright but looking for other firms.... Also does anyone have any idea how difficult it is to get a green card? And if you need one for one or two years of working in the US? And does this apply to self-employed traders?
