i am in nigeria and am inviting a friend to nigeria..but the nigeria embassy is far away from where my friend live..does she need to mail her document to the embassy for interview or must she go to the embassy for the interview .
Also how many weeks does the embassy gives before the interview date
What is the cost ?
Your friend will need to start the visa process for Nigeria using the embassy's online portal - https://portal.immigration.gov.ng/index.htm
She will then be called for an interview. If there is no Nigerian embassy in the country, then she will be required to another embassy which deals with Nigerian visas.
The amount of time the visa takes to process depends on the type of visa you apply for.
Have a read of the Expat Arrivals page on Visas for Nigeria to get a more detailed overview of the process.
Good luck,
Shantalie
