Looking for a job is your own business. Someone else hired you, not your uncle and grandfather.

In terms of the knowledge that can be learned, American universities are more cost-effective than graduate students. If you plan to recruit a job in America, it depends on your major and what job you are looking for. For example, a university professor must be a doctor. But in general, it is very important to have real skills when looking for a job in the United States.
