The United States government has defended its recent revocation of valid visas issued to Nigerians, describing the move as a national security measure.
This comes as the U.S. Embassy in Nigeria issued a fresh security alert on Tuesday, warning American citizens against unnecessary travel to military and government facilities, particularly in Abuja.
Reports earlier in the week revealed that dozens of Nigerians — including students, business professionals, frequent travelers, and families — had their visas revoked without prior notice. Former NNPC spokesperson, Femi Soneye, raised the alarm, saying many affected individuals received formal letters instructing them to submit their passports to the U.S. consulate, only for their visas to be cancelled.
In response, a U.S. Embassy spokesperson told BBC News Pidgin that the cancellations are in line with Section 221(i) of the U.S. Immigration and Nationality Act (INA), which empowers consular officers to revoke visas if there is an indication of potential ineligibility.
“We use all available information to carry this out on a scale never seen before to keep American borders secure and communities safe,” the spokesperson said.
The Embassy stressed that visa revocations may apply to individuals who overstay their visas, engage in criminal activities, provide material support to terrorist organizations, or otherwise violate U.S. laws. It added that the process is part of broader efforts to protect national security under existing U.S. immigration policies.
Meanwhile, the U.S. Mission in Nigeria advised its citizens to avoid travel to military and government facilities, citing “continued security concerns.” The advisory also urged Americans to steer clear of large gatherings, stay alert in public places, and review their personal security plans.
The warning follows a series of similar alerts in recent months, including incidents near Mogadishu Barracks in Abuja, advisories over religious commemorations, and cautions against visiting sensitive locations.
The latest notice, dated September 2, 2025, reinforces restrictions already in place for U.S. Mission staff, who are allowed to visit such locations only for approved official duties. The Embassy linked the advisory to heightened global security developments and urged vigilance, especially in areas frequented by Westerners, expatriates, and government officials.
