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.
The number of people from sub-Saharan Africa studying in the US was highest in 2020 — 41,697. Here is the trend of sub-Saharan African, West African, and Nigerian students in the US from 2001 to 2020.
In 2022, the US exported $631 million worth of agricultural produce to Nigeria, with wheat the biggest export. It accounted for 76% of the exports followed by industrial ethanol (9.3%).
