Is it difficult to sign a tourist visa and then stay in the United States without identity to find a job?

You can't work formally without identity. You can only do so-called black jobs, that is, secretly work in some shops, and the boss gives you cash, but you can't get much salary.

A while ago, the United States cracked down on illegal immigrants very severely. Many people were questioned during the long-distance bus ride.

The United States is not as good as it is now, and there are many problems. If you work hard at home, you can get along well.
