They might be there to learn it, but I am betting that most-to-all resort back to their native language as soon as they are out of there. I see this crap everyday at work, I work where there are people from all nationalities and even after 5 years, they speak English like crap and you have a very hard time understanding them......It's all because we do not have a national language and the screw balled politicians won't vote one in.
