Can ordinary China people travel to the United States?

Of course it's possible. As long as all the information is well prepared and the conditions are good, it is relatively easy to apply for a US visa. In fact, the visa officer saw nothing more than these points:

See if you have ever been to a developed country as developed as the United States, such as Europe or Australia.

See if you're married and have children.

See if you have a stable job.

Look at the assets in your name.

See if your household registration is in a sensitive area.

You can compare your information comprehensively to see if they all match. If everything is good, it will be easier for you to sign an American visa.
