Nowadays the life is changing very fast! It is not wonderfully, that you are living in USA 5 years and still has a problem to English. I think, the best way to improve language it is find a job any job, where employees are speaking only in English and nobody doesn't know your mother tongue. I think, if you want reallly to improve here, you have to engaged a teacher. Just talking to friend doesn't give you real improving. of course, you can improve here, but it will take so long time))))) And I notice, that the native English speakers doesn't want to talk to people who is learning English. Here is like a market, if you are native speaker some language and your language to need to native speakers, that he or she will to talk to you. And, first, he will try to talk in your language than in English.
