I'm one of aerocone immigrations clients, The company is not just in Nigeria, i made my research before hiring them.
To me, they are one of immigration company that Nigerians should pray to have as travel agency, I never believe one can get a work visa from Nigeria before, i cannot even believe it until when I got to the embassy and they were asking me how I did it and who helped me with it.
Pls patronize them, and exercise patience for success
