What does it mean to be a second-class citizen in America?

Refers to people who immigrate to the United States but have no social foundation in the United States.

Americans have the same human feelings, but in the American cultural system, they don't abuse human feelings like us. Only when nothing happens, because the United States is rich in materials, these people's second-class citizenship is temporarily covered up, and they feel no different from ordinary Americans, but once something happens, these people will obviously be marginalized.

This is mainly related to social foundation, and has little to do with skin color. If you have lived in the United States for generations, intermarried with local people and have deep social ties, you will get rid of your status as a second-class citizen.

Of course, if you are not fair-skinned, it will be difficult for you to integrate, which is a difficult model.
