In a January 31, 2020 Presidential Proclamation, the administration expanded its travel ban on travelers from six additional countries: Eritrea, Kyrgyzstan, Myanmar, Nigeria, Sudan, and Tanzania. The new ban (Travel Ban 4.0) becomes effective on February 21, 2020. Travel Ban 4.0 contains restrictions on immigrants but not on nonimmigrants. Therefore, Travel Ban 4.0 will not impact acquisition of nonimmigrant visas like F-1 student, J-1 exchange visitor, H-1B worker, etc., or of admission to the US in those categories. Meanwhile, Travel Ban 3.0 continues in effect on certain citizens of Iran, Libya, North Korea, Syria, Venezuela, Yemen, and Somalia.
