While many COVID-19 travel restrictions have been removed, all nonimmigrant foreign nationals continue to be required to present proof of being fully vaccinated against COVID-19 in order to board an international flight to the United States.

A summary of the COVID-19 vaccination requirements can be found below.

Someone is “fully vaccinated”:

• 14 days after receiving one dose of an approved single dose vaccine;
• 14 days after receiving the second dose in a two-dose series vaccine; or
• 14 days after receiving two doses of any approved “mix and match” combination administered at least 17 days apart.

The CDC has a list of approved vaccines. Boosters are not required.

Acceptable proof include the following:

• Vaccination certificate with QR code or digital pass via Smartphone application with QR code
• Printout of COVID-19 vaccination record or certificate issued at a national or subnational level by an authorized vaccine provider
• Digital photos of vaccination card or record, downloaded vaccination record or vaccination certification from an official source, or a mobile phone application without a QR code
• All proof must have personal identifiers (full name plus at least one other identifier such as date of birth or passport number) that match passport or other travel documents
• Airlines will determine is when a translation is required

The following are excepted from the requirement to provide proof of vaccination:

• Those on official government business or diplomatic travel
• Children under 18 years of age
• Participants in certain COVID-19 vaccine trials
• Persons with medical contraindications to vaccination
• Persons issued humanitarian or emergency exception
• Persons with valid nonimmigrant visas (except B-1/B-2) who are from countries with limited COVID-19 vaccine availability
• Members of U.S. Armed Forces and their spouses and children (under 18 years old)
• Sea crew members on C-1 or D nonimmigrant visas
• Persons whose entry is in the U.S. national interest as determined by the Secretary of State, Transportation, or Homeland Security (or their designees)
• Individuals who are excepted may have to agree to following certain protocols upon entry into the United States

In addition to the above COVID-19 travel restrictions, when traveling to the United States, all nonimmigrants should carry a passport valid for at least six months and a valid U.S. visa stamp or ESTA approval (if eligible).
