That’s not how visa bans work ‘As a result, the Secretary of State may order U.S. consular officers at U.S. embassies and consulates in these countries to implement visa restrictions on certain categories of visa applicants. These sanctions may remain in place until the Secretary of Homeland Security notifies the Secretary of State that removal cooperation has improved to an acceptable level.’
The names of those sanctions have most likely already been uploaded to the US embassies and consulates in Israel, waiting to be denied if they go and try to get one.
