Regarding employment in the United States, which professional immigrants and employment are better?

Medical talents are very much needed in the United States, but the United States does not recognize medical qualifications from any non-English-speaking countries, so all medical-related majors are not helpful for applying for immigration.

The law is also not recognized, because the United States does not trust China's judicial system, so studying law is not helpful for applying for immigration.

The most useful should be science or engineering, and the less popular the better.
