Subject to Regularization is issued primarily based on the availability of quota especially in the case of private organizations. STRs are issued on request by sponsoring organizations and individual investors coming to Nigeria to reside. It is required by foreigners coming to take up employment in Nigeria and issued according to the dates as specified in the contract. It usually allows for one single entry to foreign nationals who have the intention to obtain a long-term work permit.
However, an STR in itself is not a work permit. It is usually granted for 90 days within which an application must be made to regularize the recipient’s stay. Failure to do this will cause for a reapplication of another STR visa.
