US Immigration Policy 202 1 All people who enter the United States by air must issue a negative nucleic acid test certificate.

The situation of COVID-19 epidemic abroad is still out of control, and a large number of cases increase every day, which has not been completely solved. Recently, the U.S. Centers for Disease Control and Prevention announced that many passengers flying to the U.S. will not board the plane unless they have a negative COVID-19 nucleic acid test certificate.

The United States will require all international flight entrants to provide virus-negative certificates. The CDC announced on Tuesday that all passengers flying to the United States must show their COVID-19 negative certificates before boarding, otherwise airlines will not be allowed to board.

This test must be completed within three days before the plane takes off, covering all passengers going to the United States, including American citizens returning home. But some people can be exempted, including crew members, American soldiers and babies under 2 years old.

Robert. Redfield, director of the CDC, said that this requirement can't completely eliminate the risks, but together with other preventive measures such as wearing masks, it can really make travel safer.

The statement said that airlines must confirm documents with negative test results or rehabilitation certificates before all passengers board the plane. If the passenger does not provide the relevant documents, the airline must refuse the passenger to board.

According to the statement, variants of COVID-19 virus are constantly appearing in countries all over the world, and there is evidence that some of them are more infectious than their original strains. As the United States has entered an epidemic emergency, requiring passengers to take COVID-19 test will help to slow down the spread of the virus.

The Latest Entry Requirements of the United States At the end of last month, in view of the discovery of a new COVID-19 virus in Britain, the United States government put forward this requirement for tourists from Britain. At that time, when this request was made, the United States had not confirmed whether anyone infected with this virus variant had been found.

Because the coronavirus pneumonia-19 mutant virus found in the UK may be more contagious, the US government announced that all air passengers from the UK must attach a negative screening certificate for 20 19 coronavirus disease (coronavirus pneumonia-19) within 72 hours before boarding.

But later, this virus variant was discovered all over the world, and the United States was no exception. According to the current policy of the United States, British, European and Brazilian visitors to the United States are prohibited from entering the country if they are not Americans or permanent residents.

Cetron said that after the past holidays, the number of cases in the United States continued to increase, and more people arrived in the United States by international flights every day, which made it necessary to strengthen imported prevention and control measures.

The recent situation of international flights in the United States shows that although the number of international flights entering the United States has decreased significantly compared with a year ago, the number of international flights entering the United States has increased sixfold from June to1October, reaching165438+1October.

Cetron said that if people choose to ignore the warning not to travel, it is necessary to take measures to make travel as safe as possible.

American Airlines expressed its support for this move and called for this move to replace the current one-size-fits-all ban on passengers from some areas.
