On January 31, 2020, the Trump administration announced suspension of entry into the United States for nationals of six new countries, with some exceptions: Burma (Myanmar), Eritrea, Kyrgyzstan, Nigeria, Sudan, and Tanzania, “until those countries address their identified deficiencies” related to security and information-sharing issues. The proclamation specifies that the restrictions generally are on immigrant visa travel by those outside the United States and not on nonimmigrant visa travel. The proclamation exempts special immigrant visas for those who have helped the United States.
The proclamation states country-by-country exceptions to the ban. For example, diversity immigrants, but no others, from Sudan and Tanzania are suspended. The proclamation takes effect on February 21, 2020.
