I went to the United States to study PhD and applied for a full scholarship. Do I need proof of property when I get a visa?

As long as you have a bank deposit, you can apply for a real estate license. When you go to the United States, you must make it clear that it is a full prize, that you must return to China after graduating from college, and then give some reasons for returning to China. They refused the visa not because you wanted to emigrate because you had no money, but because many people answered in front of you that they wanted to emigrate.
