Will English level affect the application for immigration to the United States?

It depends on what kind of immigrant you are. I married an American citizen. My wife is very good at Chinese and doesn't understand a word of English. Now I have a green card and have been naturalized for two years. I don't need to be evaluated. If you invest in immigration, you don't need to be good at English. I only know that you can't get a visa when you apply for an interview to study abroad, so it depends on how you apply for a green card. Call me if you have any questions, and I'll answer you!
