Can I go back to China to study for a master's degree after studying in the United States?
Good, but it's no use coming back. Foreign education is lenient and strict, and you can learn something, but at home it is just the opposite! Besides, you can't learn anything in China. If you are preparing for coming back later, I still suggest that you study abroad first, and then come back to find a job. Then the salary may be higher than your current way!
