What exactly does the certificate of deposit used for American individual tourist visas mean?

1, can be deposited one after another, as long as there is 5w when issuing the certificate. Take the passbook to the bank and tell them to open a real estate license. They ask you how long it will take, and then put a stamp on the first page of your passbook, which says that the assets will be frozen from the day of Na Yue to that year, month and day.

You can do it before you apply for a visa or after you come back. For example, I applied for a visa in June 1 and intend to travel to the United States until August 1, then the deposit certificate should be from May 20 to August 15.
