What happens to US visa applicants from Thailand who were approved before the January travel ban but haven't had their embassy interview?

Looking for some information: Since Trump put down the “ no visa “ mandate in January does anyone know what happens to people that were approved before that happened but hadn’t had their embassy interview yet? I’m thinking one of three things might happen;

1. You get the visa and can go to the USA because you were already appointed and the mandate affects people that had not been approved before the mandate

or

2. You get approved for the visa but cannot immigrate until the mandate is lifted

or

3. You are denied and it’s just too bad so sad you’re stuck like chuck. And that sucks. All the time and money wasted.

I haven’t heard about what’s happened to anyone in this process and it would be great if NVC would put out info on the possibilities. The limbo is very frustrating. I’ve heard they go on a case by case basis but more basic info would be helpful.
