The United States of America has imposed an immigration visa ban on Nigeria.
According to The Wall Street Journal, “citizens from Nigeria, Eritrea, Myanmar and Kyrgyzstan won’t be allowed to apply for visas to immigrate to U.S”
It quoted Chad Wolf, acting secretary of the Department of Homeland Security, as saying the new immigration restrictions were designed to “address security concerns in the way the banned countries track their own citizens, share information with the U.S. and cooperate on immigration matters”.
