Wow, very impressive! What states and cities have you been to?
We are from Belarus and my aunt taught herself English just by reading a dictionary and when she came to the USA she got a job helping immigrants find work. My mom only studied the English language at high school in Belarus and just last year got a job here in Washington as a medical interpreter.
I am very impressed with people who know more than one language. I, myself try to speak Russian as much as I can for practice because I know that it is easy to forget, and grammatically I am probably not very good.
