There are lots of comments in this thread about people including myself trying to get a clear picture. There has been no clear picture.That raises another question.
I am a valid US Visa holder attempting a soft landing in Canada. If somehow the landing formalities are completed and a U-turn is possible (assuming that the 14 day quarantine does not apply), is DHS going to allow people back into the US?
Hoping someone has an answer to this.
You can try calling CBP and add what you find out to the thread
Based on my conversations with CBP :
1. If you have a valid visa you can travel via air without issues.
2. Land border seems to vary based on port of entry. When I spoke with Detroit POE they said they will allow work visas to enter, but main CBP helpline seemed unwilling.
