Who can enter USA now?

I am not from the banned area with B visa. However, when I buy ticket my staff of airline told me that only have B visa cannot enter USA now, even if I am not from banned area, is it correct? Do anyone enter USA recently?

Update: I am from Hong Kong and hold a Hong Kong passport, I am back to HK since this April and have no travel since then.

My flight will transit in ICN airport, Korea.

Best Answer

Airlines go by the TIMATIC database, which states:

--Passengers who have transited or have been in Austria, Belgium, Brazil, China (People's Rep.), Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Iran, Ireland (Rep.), Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland or in the United Kingdom (excluding overseas territories outside of Europe), in the past 14 days are not allowed to enter the USA.

(followed by exceptions)

So if you've stayed outside these countries in the past 14 days, you're allowed to enter the USA.
