Where to meet nigerians in cuba

Cuba has very few immigrants. About 5,000 Russians decided to remain there following the implosion of the USSR communist bloc, preferring to stay rather than returing to the austerity of the remnants of the Soviet Empire. But unlike Europe where many of the countries have an hospitable policy towards immigrants and where employment is possible, Cuba has difficulty in finding employment for Cubans. Over two million tourists visit Cuba each year, 45% (920,000) being from Canada. Cuba unlike Canada, does not have various ethnic or multicultural organisations through which it is possible to meet compatriots. So, I don't think that you will meet Nigerians there. Regarding visiting Cuba, you have  two choices - book a package tour and stay for example in Varadero where there are 57 hotels or go single using buses (Viazul) to tour around the country and stay in Casa Particular (Bed & Breakfast). It is helpful if deciding to go solo, to have a little Spanish.
