Nigeria requires Citizens of most countries to obtain a valid visa to enter the country. The Consulate General determines the duration of stay upon receiving an application.
Tourist Visa
The Nigerian tourist visa is issued with a validity of three months, and is intended solely for applicants wishing to visit the country for the purposes of tourism, or visiting friends and relatives.  However, applicants must leave upon the visa’s expiry and must not engage in any form of employment while on their visit.
Business Visa
A Nigerian business visa can be granted to foreign nationals wishing to travel to Nigeria on a temporary basis in order to attend meetings, conferences and engage in other business activities.  However, under no circumstances may they engage in any form of Nigerian employment.
The Nigerian business visa is issued at a standard length of 90 days validity.  However, this can be extended, if necessary.
