Is there a handling fee for China CITIC Bank to pay the US visa fee?

CITIC Bank is a place where you can pay visa fees in the United States. You just need to give them a visa fee, and then you can make an appointment for an interview at the American embassy. In fact, you can find an intermediary to apply for a visa to the United States, because the United States belongs to a developed country after all, and there is a certain chance of refusing a visa. Even if your information is no matter how good, you may be refused a visa directly, so it is best to find a professional institution when handling it.

But now there are more and more people who want to travel to the United States, so there is an endless stream of applicants. Obviously, there are more and more institutions handling American visas now. Because of this, many applicants can't tell which is more professional when applying, so they must find a professional intermediary.
