When you use otherwise, it is to compare and contrast two different outcomes to a situation.  For example, I need to study English a lot, otherwise, I wont be able to go to college in America.

Once again great job, I could understand exactly what you wanted to say, and you would have no problem living in America and being understood.  Keep up the good work :-)
