Africa is the hardest-hit region, with 14 countries under partial visa restrictions, including Nigeria, limiting travel for business, tourism, and study.
Temporary bans target B‑1/B‑2 visas for business and tourism, and may also affect F‑1 student, M‑1 vocational, and J exchange visitor visas, impacting students, trainees, and cultural exchange participants.
Other affected regions include the Caribbean, Asia, and South America, showing the temporary restrictions span multiple continents.
Exemptions exist for lawful permanent residents, diplomats, and travellers with valid pre-existing visas, so not all citizens from these countries are blocked from entering the US.
