How to work abroad? Can you get a tourist visa first, go there first, and then look for a job when you go abroad?

Yes or no, not legally, because you can't find a job at all without a work permit, and you are not allowed to find a job. But when you arrive in the United States first, you can find a reliable labor service company or law firm and turn it into your work visa. Of course, there are also many liars. It depends on whether you can find it. The best way is for you to find an intermediary in China, and the intermediary will apply for the H 1B visa in the name of labor dispatch, so that you can see the H 1B visa before going to the United States. If you can't get down, you don't have to go. It's no use going.
