Entry protocol

For general measure

All airline passengers two years of age and older traveling to the United States must give a negative COVID-19 viral test done within 1 day before your your flight. Additionally, visitors visiting the United States may present proof from a qualified health care physician that they have recovered from COVID-19 in the 90 days before to travel.

Children under the age of two, crew on official duty, certain federal law enforcement employees, members of the US military, and individuals with humanitarian exemptions granted by the CDC are excluded from the negative test or verification of recovery requirement, according to the CDC’s Order.

To validate the negative test results or evidence of recovery, all passengers on air transportation must complete the attestation. If you are completely vaccinated or have recovered with COVID-19 within the last three months, you do not need to get tested or self-quarantine.

The United States forbids travellers from the following countries where omicron is spreading:

  • Botswana
  • Eswatini
  • Lesotho
  • Malawi
  • Mozambique
  • Namibia
  • South Africa
  • Zimbabwe

  • They should keep taking COVID19 precautions while traveling, such as wearing a mask, avoiding crowds, socially separating themselves, and washing their hands often.

Vaccines acceptable for entrance into the United States will include those that are FDA approved or authorized, as well as those on the WHO Emergency Use List.
  • Beginning Nov. 8, the United States will accept fully vaccinated foreign air travelers from the 26 Schengen countries in Europe, which include France, Germany, Italy, Spain, Switzerland, and Greece, as well as the United Kingdom, Ireland, China, India, South Africa, Iran, and Brazil. Also, the White House has stated that beginning Nov. 8, it would open its land borders with Canada and Mexico to fully vaccinated passengers.
  • However, all air passengers arriving in the United States, including U.S. citizens and fully vaccinated people, must have a negative COVID-19 test result no more than 3 days before travel or documentation of recovery from COVID-19 in the previous 3 months before boarding a flight to the United States.
  • Regardless of vaccination status, international visitors traveling in the United States are still advised to have a SARS-CoV-2 viral test 3-5 days after arrival. Travelers who are fully vaccinated do not need to self-quarantine in the United States after returning from a foreign trip.

For recovered travellers,

  • The Centers for Disease Control and Prevention (CDC) within the Department of Health and Human Services (HHS) issued an Order on January 12, 2021 requiring proof of a negative COVID-19 test or documentation of having recovered from COVID-19 for all air passengers arriving from a foreign country to the US.
  •  To validate the documentation of recovery from COVID-19, the passenger must complete all six of the standards listed below:
    • The test is a viral test. Please refer to the negative test requirement for the allowed test.
    • The test must indicate where the test was done as well as information like the name and contact information for the laboratory or healthcare staff who performed the test.
    • The specimen collection date for the test must be within the past 90 days. Tests older than 90 days do not qualify for option B; instead, the passenger must meet the conditions of option A (Proof of negative test results)
    • The information that identifies the person must be included in the test.
      • It must be the person’s name on the documentation. Additional identifiers may include, but are not limited to, the date of birth, age and passport number and at least one other identifier.
      • Check that the identifiers on the test correspond to those on the passenger’s other identification documents (or something like a passport or driver’s license).
    • The test must yield a positive result. “Invalid” results are not accepted. Among the phrases used to describe a positive test are, but are not restricted to:
      • POSITIVE
      • REACTIVE
    • It must also include a signed document verifying that the passenger is authorized to travel.

      • Must still be signed and on official documents with the healthcare provider’s or public health official’s name, address, and phone number.
      • It is not necessary to specify travel—a letter releasing the individual from isolation (e.g., to return to work or school) can suffice.
