The Trump administration has ordered a social media vetting for all US visa applicants who have been to the Gaza Strip on or after January 1, 2007, in an effort to tighten screening of foreign travelers. The vetting will include non-governmental organization workers and individuals who have been in Gaza in an official or diplomatic capacity. If potential derogatory information is found through the social media review, a security advisory opinion must be submitted. The move comes as the administration has revoked hundreds of visas across the country, including some lawful permanent residents.
