Trump Administration Adds Six Countries to Travel Ban
President Trump added Africa’s biggest country, Nigeria, as well as Myanmar, Eritrea, Kyrgyzstan, Sudan and Tanzania, to his restricted travel list.

Immigrant visas, issued to those seeking to live in the United States, will be banned for Nigeria, Myanmar, Eritrea and Kyrgyzstan. The ban will also prevent immigrants from Sudan and Tanzania from moving to the United States through the diversity visa lottery, which grants green cards to as many as 50,000 people a year.
The proclamation will take effect on February 22.
