He is so frustrated and thinks he made a bad decision to jump on the going-abroad wagon. He has been here in the US for 4 years, no green card so cannot apply for self-support, doing hard lab work with less pay and is afraid of boss losing funding.

I asked why you did not go back to China. He said it was very hard to find a job in the institutions in the major cities.

He is currently doing microbiology and gene therapy research.

I felt sorry for him.
