This is in addition to the normal visa application fees of between $160 and $190.

“The total cost for a US citizen to obtain a visa to Nigeria is currently higher than the total cost for a Nigerian to obtain a comparable visa to the United States.

“The new reciprocity fee for Nigerian citizens is meant to eliminate that cost difference,” the US Embassy said at the time in a statement on its website.

In his letter, the NIS boss urged all Nigerian missions in the US to immediately implement the new visa charges payable by US citizens, and “discontinue charging processing or expedient fees”.

“Our Missions are to issue up to two years multiple entry visa to frequent short visit travelers on request in line with reciprocity,” he said.

NAN said it received information from a senior official of the Nigerian Consulate in New York that the “processing and expedient fees” of $20 was for online application and payment services rendered by a private firm.

The move follows the unveiling by President Muhammadu Buhari of Nigeria Visa Policy 2020 which increased the country’s visa classes from six to 79.
