From February 22, the United State will begin a new Visa regime which would further restrict the ability of immigrants from Nigeria and five other countries.
US President Donald Trump had last year threatened to impose such restriction on Nigeria and other countries with high number of immigrants in America.
According to reports from Washington D.C, Trump signed a proclamation approving the restrictions on Friday afternoon.
The proclamation will curb the ability of citizens of Nigeria, Myanmar, Eritrea, Kyrgyzstan, Sudan and Tanzania to get certain immigration visas, according to officials with the Department of Homeland Security and State Department, but it is not a blanket travel ban.
The officials cited national security concerns in identifying those countries, saying those governments do not meet requirements for information-sharing and passport security.
The announcement comes just over three years after Trump first announced he would impose a travel ban targeted at several Muslim-majority nations. An altered version of that ban was later upheld by the Supreme Court, and travel from Iran, Libya, Syria, Somalia, North Korea, Venezuela and Yemen is still restricted.
The hill.com reported that the expanded ban is certain to be challenged in courts. It said that former diplomats have expressed confusion over the inclusion of Nigeria in particular, warning that restricting travel from some of those countries will harm American interests.
