The US administration has announced that the ban imposed on eight African countries amid the Omicron's emergence will be lifted on 31st Dec. 2021. Travelers will still need to follow the recommendations of the US CDC. The American authorities announced that the current restrictions helped to understand the nature of the Omicron and make sure that the existing COVID-19 vaccines work against this variant, especially booster shots.  Similar Omicron-related restrictions were also imposed by the European Union, Canada, and the United Kingdom. The United Kingdom and Canada already lifted the ban.

The negative test result will be required to show before boarding the flight to the States. All travelers entering the United States by air who are aged 2 years or older need to provide a negative test result.  Certificate of COVID-19 recovery Those who recently recovered from the coronavirus may alternatively enter the US with a recovery certificate confirming that they have been tested positively against COVID-19 no earlier than 90 days prior to the departure flight from their country. A letter issued by a licensed health authority stating a traveler's ability to travel is also necessary.
