Whats the best advice i can get to travel to the USA?

I want to travel to the USA as a UK citizen to train as a professional wrestling school in Florida. I understand that i can only stay for up to 90 days as a UK passport holder. My training is probably going to take around 6 months in all. Is this possible and if so how can i get around the 90 day thing? I have spoken to the trainer and they have had overseas students before so it must be possible. However a few other wrestling schools replied saying that i'd have trouble getting into the USA. I don't understand, I haven't got a criminal record, good law-abiding citizen and i just want to go to the states to do my training as it has the most reputable wrestling schools. Please can someone help with this, requirements both this end and in the USA, if any. Your help would be greatly appreciated.

Its the same for musical acts that tour in USA, they have to get a temporary working visa (i think it last for 6 months). phone the USA Embassy and see what they can tell you :)

go to the american embassy and buy a visa. i overstayed my 3 months before and now i have to get a visa every time its not worth doing because they can refuse you entry as well

Dont go its full of Americans and they will Eat you lol.....

you can go aply for a green card at the immagraition office just telll them why you want it and why you are wanting to be in the us there are a lot of people here whith those i know a lot of people in this area that are not us citizens that have been here for years.

If it's a real school you can get a Student Visa to enter as long as your going to school. The US has been a bit hard to get into lately.

Hey boss, check it out with the school you are affiliated with. The training center will be happy to work with you. It is funny, but American schools love to help with things like that. There is a 180 degree difference between customer service in the US compared with Europe. When I was looking into schools in Europe I couldn't get anyone to help with anything but the Americans where great at getting me what I needed and they were nice as hell to boot. Just give the training center a call and they should sort you out. Don't be afraid to ask for exactly what you want.
