Message from US Embassy Tel Aviv Consular Section (updated as of 21:30 Israel time):
Travelers with an existing valid visa in their Israeli passport may travel to the United States, even if they are also a national of or born in one of the seven restricted countries (Iraq, Iran, Libya, Somalia, Sudan, Syria, and Yemen). Embassy Tel Aviv will continue to process visa applications and issue visas to eligible visa applicants who apply with an Israeli passport, even if born in, or a dual national of, one of the seven restricted countries. Final authorization to enter the United States is always determined at the port of entry.
