Want to work abroad, the United States, how to apply for a visa passport? I come from Jinan

To work in America, you need to apply for immigration. Only immigrants can legally work in the United States! Or starting a company in the United States is also a form of immigration, that is, L 1 work visa! There is also a business trip, which requires a guarantee from a foreign company, not a job! Passports should be handled at the local exit-entry management hall, and American visas should be reserved, and then they should be signed by themselves.
