I am in USA on H1B visa. There is an understanding by some Americans that we do not assimilate. What is assimilating? how to assimilate?
I am in USA for last 11 years, I don't know when I will get green card and my kids are aging out. I am always under pressure that I may have to go back anytime given the fact that after layoff H1B can stay in USA only for 60 days and now more as getting a job has become harder.
