*** Update ***
The latest travel ban is due to go into force tomorrow. However, today, a judge in Hawaii has blocked the ban, in the same way that the previous ban was temporarily blocked. That previous block did provide some relief for some cases, at least for a period of time. This is very much developing news, it is FAR too early for me to answer questions about what this latest block will mean.
I don’t yet know what the impact will be for any specific cases.
Also, the ruling will most certainly be appealed and the case will probably end up in the supreme court. So – time will tell as to what this means.
