The SEVER Act of 2023 would prohibit the United States from issuing visas to individuals who are subject to sanctions under Executive Order 13876, which targets entities and individuals involved in Iran's activities. The bill specifically applies to representatives to the United Nations and other foreign nationals seeking entry to the United States. By expanding existing visa denial authority, the legislation aims to strengthen enforcement of Iran-related sanctions by preventing sanctioned individuals from entering the country. The bill does not specify new funding requirements or implementation timelines beyond the amendments to existing visa authority. This measure would affect foreign diplomats and nationals from Iran or entities working with Iran who are under U.S. sanctions.
