I just returned to Europe from home from a 30 days business trip to Lagos, and I decided to move there permanently and to start my own consulting business. My question: What type of visa/residence permit do I need? STR (Subject to Regulation Visa) and CERPAC (Combined Expatriate Residence Permit and Aliens Card for Nigeria) both require an employment contract, but as I said - I aim to start my own business. I want to avoid going back and forth every 3 months on a business visa. I haven't set up a business in Nigeria yet, I plan to do this during my next stay in Lagos.
