There are several kinds of workers who go to America. A friend told me that there are migrant workers, and a friend told me that there is a work permit that only lasts for three years.

The general labor market in the United States is not open to China citizens, and China citizens do not have labor visas.

Just want to work in America:

1. professional immigrants (that is, the migrant workers you mentioned), EB 1, 2, 3. Ordinary people need to have an American employer in advance to apply for EB3. The waiting period is long, which generally takes nearly 10 years. Whether you can succeed in the end depends on the final attitude and operation of this American employer.

At present, some unscrupulous EB3 immigration projects in China are basically deceptive.

2. H1B. This is a three-year and six-year work visa. You need a bachelor's degree or above, have a professional counterpart, be employed by an American company, and you can't recruit corresponding employees in the American market.

3. Smuggling, illegal labor.
