I am a US green card holder (PR), citizen of Canada, UK, NZ. Currently I wouldn't consider travelling outside of the US except to the countries I am a citizen of. There's too much that can potentially go wrong and I'd rather wait and see how things go.
Luckily I have three options but even then I'm probably not going anywhere soon.
Personally, I believe this will become a pandemic and the travel restrictions will become pointless. However maybe I will be wrong. I'm more afraid of getting stuck outside of the US than the virus itself.
