The Supreme Court has upheld the travel ban. They were split 5-4 on “party lines”, meaning Justice Gorsuch (appointed by Trump) delivered him his victory. That is the final verdict and means the terms of the travel ban as currently in place will continue as long as this administration wants, or Congress changes the law. That is a blow to people from the banned countries, and effectively destroys the hopes of thousands of DV selectees in DV2018 and DV2019.
So – if you are affected by the travel ban (and do not have dual citizenship) you should not even interview unless you feel you have some sort of exception that applies to you.
