Children should return to full-time in-person learning in the fall with layered prevention strategies in place.

UPDATE
The White House announced that vaccines will be required for international travelers coming into the United States, with an effective date of November 8, 2021. For purposes of entry into the United States, vaccines accepted will include FDA approved or authorized and WHO Emergency Use Listing vaccines. More information is available here.

Get Started

Land TravelFor information about COVID-19 requirements for land travel and at ferry terminals, visit the U.S. Department of Homeland Security’s Fact Sheet: Guidance for Travelers to Enter the U.S. at Land Ports of Entry and Ferry Terminals.

Before You Leave the United States
Make sure to plan ahead:

Get up to date with your COVID-19 vaccines before you travel.

Find out when you can get your booster and where to get a vaccine or booster.
COVID-19 vaccines are effective at protecting people—especially those who are boosted— from getting seriously ill, being hospitalized, and even dying.

Follow all requirements of transportation operators (such as airlines, cruise lines, buses) and any requirements, including mask wearing, proof of vaccination, or testing at your destination.

Requirements in other countries may differ from U.S. requirements. If you do not follow your destination’s requirements, you may be denied entry and required to return to the United States.

If you have a weakened immune system or are at increased risk for severe disease, take multiple prevention steps to provide additional layers of protection from COVID-19 even if you are up to date with your COVID-19 vaccines.

Talk to your healthcare provider about your risk before travel and consider delaying travel to areas with high COVID-19 levels. Even if you are up to date, you should know what precautions to take.

If you will be visiting someone who is at higher risk of getting very sick from COVID-19, learn how to protect them.

Testing
