American visa problem! It is said that the visa officer will give a note to the post office after the American visa is passed. Explain the process in detail.

Before applying for a visa, you will buy a phone card and visa fee from China CITIC Bank, and the bank will give you a courier. You will write down your home address on the courier, and the staff will receive your courier on the day of face-to-face receipt. If it passes, your passport will be taken away by the visa officer and you will receive it within one week.
