The Nigeria Immigration Service (NIS) has launched a nationwide operation targeting foreign nationals residing in the country without valid immigration documents following the expiration of a three-month amnesty granted by the Federal Government.

The amnesty, which opened on July 5 and lapsed at midnight on September 30, allowed foreigners with irregular immigration status to regularize their stay without penalties.

According to the NIS spokesperson, Akinsola Akinlabi, said in a statement on Wednesday, “With the expiration of the amnesty period, effective October 1, 2025, enforcement actions will commence nationwide against foreign nationals who have overstayed their visa or violated their entry conditions.

The exercise targets holders of expired Visa on Arrival, expired single and multiple-entry short visit or business visas, and individuals with expired Comprehensive Expatriate Residence Permits and Automated Cards.

Foreigners caught in violation face removal, daily fines, or entry bans. Overstayers of less than three months risk deportation, a $15 daily fine, or a two-year entry ban. Those who overstay between three months and one year face removal, daily fines, or a five-year entry ban, while individuals exceeding one year risk deportation and up to a 10-year or permanent entry ban.

The Service said the measures are aimed at safeguarding national security and ensuring strict compliance with immigration laws.

Interior Minister, Olubunmi Tunji-Ojo, had earlier warned members of the diplomatic corps to advise their nationals to take advantage of the amnesty window, stressing that Nigeria’s immigration laws “are not meant to be abused but respected.”

Furthermore, the NIS explicitly warned Nigerian individuals and corporate entities that anyone found employing or harboring undocumented foreign nationals will face prosecution under the law. The NIS urges all foreign residents to regularize their stay to avoid sanctions.
