The White House announced on the 4th that it will impose comprehensive entry restrictions into the United States for citizens of 12 countries, including Afghanistan, Myanmar, Iran, and Yemen, and partial restrictions for citizens of 7 other countries, including Burundi.
According to the White House announcement, this restriction order will take effect on the 9th Eastern Time.
The United States is enforcing comprehensive entry restrictions for citizens from Afghanistan, Myanmar, Chad, Congo (Brazzaville), Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen on grounds of "national security".
The United States will also partially restrict entry for citizens from Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela.
The announcement states that the restrictions aim to prevent "foreign terrorists and other threats to national and public safety" from entering the United States.
In January 2017, after Donald Trump first became president of the United States, he issued a restriction order prohibiting citizens from Libya, Syria, Iran, Yemen, Iraq, Sudan, and Somalia from entering the United States. This caused significant confusion at the time and led to a series of lawsuits. After taking office, Biden rescinded several of the Trump administration's restrictions.
