Isn't there an English letter for the American visa number?

If you have obtained an American visa before, the visa number is a series of red numbers on the previous visa. If it is the first time to apply for a visa to the United States, there is no visa number. If you still can't find it, it doesn't matter. Call the embassy directly and you will tell me directly.

An American visa is an endorsement on a passport or other travel document held by an American or foreign citizen, indicating that the holder is allowed to apply for entry into the United States. It can also be said that it is an endorsement certificate issued to them. American visas can be divided into two categories: immigrant visas and non-immigrant visas; Each big category can be divided into many small categories.
