Yes, it is happening....Travel in 2022
You can go now

Are there travel restrictions?

Yes, there are.

As 2022 kicks off, Africa, North, Central, and South America as well as Europe are “open”.

Australiasia and Asia are “closed”

Open means possible and with some consistency.

Closed means more challenging unless you are a diplomat or have special access (Olympic Athlete as an example)
