U.S. visas issued to nationals of Mauritania
The reports below contain preliminary data which are subject to change. Beginning with FY 2020, individual monthly issuance reports should not be aggregated, as this will not provide an accurate issuance total for the fiscal year to date. Instead, refer to our annual Report of the Visa Office for final full Fiscal Year statistics.
Nationals of Mauritania were issued 62 U.S. nonimmigrant visas in September 2025, down 52% on September 2024 (130), the 154th largest nationality of 203 in the month's table.
For the full fiscal year the Department's Report of the Visa Office lists 932 nonimmigrant visas issued to nationals of Mauritania in FY2024, 0% of the 10,969,936 issued worldwide and the 166th largest nationality of 197. The previous year's figure was 1,080 (FY2023).
The largest classes in September 2025 were B1/B2 (temporary visitor for business and pleasure) with 27, G2 (other representative of recognized foreign member government to international organization, and immediate family) with 10 and A1 (ambassador, public minister, career diplomat or consular officer, or immediate family) with 9. 20 immigrant visas were issued to applicants chargeable to Mauritania in the same month, led by DV (10) and IR2 (4).
The Department's adjusted refusal rate for B (visitor) visa applicants who are nationals of Mauritania was 67.61% in FY2025, close to the Africa median of 55.57%; it was 70.07% in FY2024. The rate covers B visas only and is the Department's own calculation, counting each applicant once by their final status in the year.
In the Diversity Visa program, 261 entrants chargeable to Mauritania were selected for DV-2026, 0.2% of all selectees that year; the count was 228 for DV-2025. Selection is not a visa; the Department's pages explain that selectees must still qualify and that more are selected than there are visas.
The U.S. post in Mauritania (Nouakchott) issued 43 nonimmigrant visas in September 2025, to applicants of all nationalities.

Adjusted B-visa refusal rate by fiscal year
Dark bar: Mauritania. Grey bar: Africa median for the same year. The Department's rate covers B visas only; it counts each applicant once, in the status in which the fiscal year ended, so an applicant refused and later issued in the same year counts as an issuance. Source tables: FY2023, FY2024, FY2025.
