Ricky Hatton is British and a champion, Lennox Lewis was Jamaican/British/Canadian and was a champ. Nationality doesn't figure into it.

Anyone can win a boxing title. Get yourself a good trainer and train very hard. Make it your passion.
You can do it if you try. Boxing is not just for Americans. I wish you good luck.
There is a lot of foreign champions. Just go for it.
ANYONE WHO IS WILLING TO PUT IN THE WORK HAS AN OPPORTUNITY, BUT YOU HAVE TO HAVE THE TOOLS TO GO WITH IT....I FOUGHT FOR YEARS BUT NEVER WENT PRO. HOPE YOUR CHIN IS GOOD AND KEEP WORKING TO FULLFILL YOUR DREAM....GOOD LUCK
Lennox Lewis is from Great Britain.
Wladimir Klitschko is from The Ukraine
Felix Trinidad is from Puerto Rico
Julio Cesar Chavez is from Mexico
Max Schmeling is from Germany

This is a VERY SHORT list of professional boxers who are foreigners that also became boxing champions in various weight classes, past and present. You may be a good boxer, but you might still be rough around the edges. It may not be nationality, but individual skill and talent level.

Rocky, as mad as it may make you, was realistically written by those who have been in the boxing pits. And if you remember ... Rocky doesn't win in the first fight against Apollo Creed. Hell, some of my friends tell me that I should see Cinderella Man (based on the true story of boxer James Braddock). Besides, movies are movies for a reason ... reality is a different story altogether.
A lot of Mexican Nationals hold titles, all by the way the Heavyweight Champ is from the Ukraine. The training in the United States seem to be better.
