On average, how many people get American immigrant visas a day?

Nothing to say. Generally, immigrant visas are not open every day, but only from Monday to Friday. Besides, they are closed during the holidays that coincide between China and the United States, and senior officials in the United States are also closed. So, you should consider this situation. The maximum number of visas is around 10- 15, which is a relatively high situation. The key depends on the interview time!
