No, but can I direct you to the British expats forum
http://britishexpats.com/forum/ Just go down to the immigration section and select the country you are interested in (there is a section on American visas) and the people over there are either going through the immigration process or have been through it and may be able to answer your questions or recommend a lawyer. There is some really helpful people over there who really know their stuff so you should get a decent answer. Best wishes.
