U.S. Entry Requirements due to COVID-19   

The U.S. has revised its testing requirement for all travelers ages 2 and above entering the U.S., effective December 6. Here’s what your travelers need to know about the new U.S entry requirements:   

The CDC created a quick reference guide “TRAVELING TO THE UNITED STATES FROM A FOREIGN COUNTRY BY AIR”, to help Travel Agents and customers better understand the U.S. entry requirements.


All travelers arriving in to or connecting through the U.S., regardless of citizenship or vaccination status, must show proof of a negative COVID-19 test taken within one (1) day of departure, or documentation of having recovered from COVID-19 within the past 90 days. Travelers who are not U.S. citizens or permanent residents must still have proof of being fully vaccinated to enter the U.S, unless they meet the criteria for an exception.


Before boarding a flight to the U.S., all passengers ages 2 and up will need to complete an attestation form.  Additionally, all passengers will need to consent to Contact Tracing. Delta will collect this information for its passengers on behalf of the CDC at check-in.    


Acceptable vaccine typesinclude those authorized for emergency use or approved by the U.S. Food & Drug Administration and World Health Organization (WHO). View the chart below for approved vaccine types.    

Vaccines approved or authorized by the US FDA  

Vaccines Listed for Emergency use by the WHO  

Single dose  



2-dose series  









Note: The Sputnik vaccine is not permitted for entry into the U.S.    

Fully vaccinated is defined as:   

  • 2 weeks (14 days) or more since a person received one dose of a single dose vaccine; or  
  • 2 weeks (14 days) or more since a person’s second dose of a 2-dose vaccine; or  
  • 2 weeks (14 days) or more since a person received the full series of an “active” (not placebo) vaccine in the U.S.-based AstraZeneca or Novavax trial; or  
  • 2 weeks (14 days) or more since a person received a complete series of a vaccine or combo of vaccines     

Proof of vaccination can either be digital or paper and will need to include at a minimum full name and date of birth matching the traveler’s passport, name of official source issuing the vaccine, vaccine type and date(s) of vaccination. Airlines will be instructed to look for this information when verifying a traveler’s health documents.  Delta will accept proof of vaccination in other languages and will have agents on-site who can verify the key elements.

View the below for proof of vaccination types.

Documentation Type


Verifiable records (digital or paper)

Vaccination certificate with QR code*, digital pass via Smartphone application with QR code* (e.g., United Kingdom National Health Service COVID Pass, European Union Digital COVID Certificate)

Non-verifiable paper records

Printout of COVID-19 vaccination record or a COVID-19 vaccination certificate issued at national or subnational level or by an authorized vaccine provider (e.g., the CDC vaccination card)

Non-verifiable digital records

Digital photos of vaccination card or record, downloaded vaccine record or vaccination certificate from official source (e.g., public health agency, government agency, or other authorized vaccine provider), or a mobile phone application without QR code*

*The QR code in a verifiable vaccination record links to information confirming the credential was generated from an immunization record in an official database and is protected from tampering.


A viral test that could be either an antigen test or a nucleic acid amplification test (NAAT) is acceptable.  Rapid tests are also acceptable if they are a viral test. For more detailed information on testing, click here.

IMPORTANT NOTE! The above requirements apply to all customers entering the U.S. even if connecting onto another international destination.


  Unvaccinated foreign travelers may be permitted to enter the U.S. if they meet  any of the following  exceptions:  

  • Persons on diplomatic or official foreign government travel
  • Children under 18 years of age
  • Persons with documented medical contraindications to receiving a COVID-19 vaccine
  • Participants in certain COVID-19 vaccine trials
  • Persons issued a humanitarian or emergency exception (obtained through U.S. embassies or consulate overseas who coordinate with CDC, which makes determinations on eligibility)
  • Persons with valid visas [excluding B-1 (business) or B-2 (tourism) visas] who are citizens of a foreign country with limited COVID-19 vaccine availability
  • Members of the U.S. Armed Forces or their spouses or children (under 18 years of age)
  • Sea crew members traveling pursuant to a C-1 and D nonimmigrant visa
  • Persons whose entry would be in the national interest, as determined by the Secretary of State, Secretary of Transportation, or Secretary of Homeland Security (or their designees)

  Note: Objections to vaccination based on religious or moral convictions do not qualify for an exception under the Presidential Proclamation and CDC’s Order.  

Visit the CDC website here for detailed information on each exception and what is required to show proof that a traveler qualifies for an exception.


Unvaccinated foreign travelers traveling by air to the U.S. under one of the above exceptions will be required to attest that they are exempted from the requirement to present Proof of Being Fully Vaccinated Against COVID-19 based on one of the exceptions listed above. Based on the category of the exception, they may further be required to attest that: 

  • They will be tested with a COVID-19 viral test 3–5 days after arrival in the U.S., unless they have documentation of having recovered from COVID-19 in the past 90 days; 
  • They will self-quarantine* for a full 7 days, even if the test result to the post-arrival viral test is negative, unless they have documentation of having recovered from COVID-19 in the past 90 days; and 
  • They will self-isolate** if the result of the post-arrival test is positive or if they develop COVID-19 symptoms. 

Based on the category of the exception, if a traveler intends to stay in the U.S. for longer than 60 days, they may additionally be required to attest that: 

  • They agree to be vaccinated against COVID-19; and 
  • They have arranged to become fully vaccinated against COVID-19 within 60 days of arriving in the U.S., or as soon thereafter as is medically appropriate, unless (for children) they are too young to be vaccinated. 

A parent or other authorized person should attest on behalf of a passenger under 18 years old. An authorized person may attest on behalf of any passenger who is unable to sign their own attestation (e.g., because they are too young, or because of physical or mental impairment). 

*Children under 18 are exempt from self-quarantine.

** Children under 18 are subject to self-isolation for at least 10 days if their test taken within 3-5 days of arriving in the U.S. comes back positive, or if they develop COVID-19 symptoms.


Any flight entering the U.S. from a foreign country, even for a connection, will require testing before departure.  

If an itinerary has the passenger arriving to the U.S. via one or more connecting flights, their test can be taken within 1 day before the departure of the first flight. 

Please note, if an itinerary incorporates one or more overnight stays enroute to the U.S., passengers will need to make sure their test is not expired before their flight will enter the U.S. Passengers do not need to be retested if the itinerary requires an overnight connection because of limitations in flight availability. 


If the first flight in a passenger’s trip is delayed past the 1-day limit of testing due to a situation outside of their control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is 24 hours or less past the 1-day limit for testing, they do not need to be retested. If the delay is more than 24 hours past the 1- day or limit, then they will need to be retested. 

If a connecting flight in a traveler’s trip is delayed past the 1-day limit of testing due to a situation outside of their control (e.g., delays because of severe weather or aircraft mechanical problem), and that delay is less than 48 hours past the 1-day limit for testing, they do not need to be retested. If the delay is more than 48 hours past the 1-day limit, then they will need to be retested.
