Does Binance work in USA?

I'm interested in cryptocurrency trading and have heard a lot about Binance, one of the largest crypto exchanges globally. However, I'm confused about its operations in the United States. Could you please clarify if Binance operates in the USA? If so, are there any restrictions or limitations I should be aware of? Additionally, I'd like to know if Binance USA is a separate entity or a part of the global Binance platform. Could you also provide any insights on the regulatory framework for crypto exchanges in the United States? Thank you for your help.
