Nigeria Immigration Services

A business visa is suitable for business visitors and generally permits a stay of up to 90 days, which can be extended in country for a further 30 to 90 days, at the authorities' discretion. Non-Economic Community of West African States (ECOWAS) nationals require an extension for any stay of 56 cumulative days or more in a 12-month period.
A Combined Expatriate Residence Permit and Aliens Card (CERPAC) or a Temporary Work Permit (TWP) are suitable for foreign nationals undertaking work, depending on their intended length of stay. Additionally, nationals of countries that are not ECOWAS members have different work authorization options than ECOWAS nationals.
Note that a same-sex spouse or unmarried partner (opposite or same sex) is not recognized as a dependent in Nigeria.
