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

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