How can I get a visa if I have an invitation to the United States?

First of all, the plane ticket can't be booked yet. When you go to America, it's easy to be refused a tourist visa. The visa process is that you pay the visa fee and phone card fee at CITIC Bank first, and then call to make an appointment for the visa time and number. Then you have to prepare the information. Your invitation letter must be true. To apply for a visa at the embassy, you need to prepare a deposit certificate to prove that you have enough economic strength to travel to the United States, and then your parents' income certificate, real estate license, car license and so on. To prove that you must return to China after your trip. Official invitations are better, and friends will basically refuse them. And if you have been to other countries before, bringing photos will help your visa.

Bless you
