All these reports about people's ESTA being canceled prior to travel got me worried. We are planning to, hopefully, finally visit family in the USA. As a spouse of a U.S. citizen, I fall within the exception and can transit the 'banned' countries. As a Ukrainian national, I require an actual visa rather than an ESTA. So, I will be flying on the B visa. Has anyone heard about any instances of the CBP canceling visas before travel due to travelling from/transiting the countries in the Proclamation? I understand that ESTA is easy to reapply for, but a visa can only be obtained at an Embassy. I don't think there is a way to advise the airline in advance about the exception. If I get to the check-in desk I can show all of the documents, but with people's ESTA being canceled hours before the flight, I am now worried.
