Since Nigeria is not one of Canada's visa-exempt countries,

Nigerian nationals must obtain a visa in advance to legally enter the country.
Visa requirements apply to all Nigerian citizens, regardless of the purpose or duration of their visit.

Before applying, they need to know the specific type of visa that best suits their travel needs.
For example, if they plan to visit Canada for a short period of time, such as to travel or visit friends and family, they will need a temporary resident visa (TRV), commonly known as a visitor visa.

On the other hand, if they are traveling for business purposes, they may need a business visa. For Nigerian citizens who are students or workers, a study or work permit is required.

To apply for a Canadian visa from Nigeria, you must go through an application process that includes submitting the necessary documents, paying the appropriate fees and attending an on-site interview (if required).

The whole process can take weeks or even months, so it is vital that you plan your application well in advance of your planned travel dates.
