While several nations, including much of Europe, remain closed to US travelers, a growing number of countries are reopening their borders to them.

Back in August, the US Department of State returned to its previous system of "country-specific levels of travel advice", which means it's once again rating individual countries from levels 1-4 based on their current health and security situations. The decision was made in line with the US Centers for Disease Control and Prevention (CDC) and advisories are updated regularly as situations evolve quickly. But despite the removal of the sweeping travel ban and the gradual roll-out of the vaccine, the department warns: "we continue to recommend US citizens exercise caution when traveling abroad due to the unpredictable nature of the pandemic."

Canada and much of Europe, Asia and Oceania are pretty much off-limits to US travelers. But some countries have begun to relax their border restrictions and are now allowing US citizens to enter provided they follow local public health guidelines. However, it's important to note that anyone aaged two and over arriving into the US on an international flight must provide proof of a negative COVID-19 test taken within 72 hours of departure . "If a passenger chooses not to present a test result or documentation of recovery, the airline must deny boarding to the passenger," the CDC says. Passengers are also required to self-isolate upon return, regardless of their result.

According to the CDC : "Get tested again with a viral test 3-5 days after your trip and stay home and self-quarantine for a full 7 days after travel, even if your test is negative. If you don’t get tested, stay home and self-quarantine for 10 days after travel."

If you do plan to travel, below is a list of where you can go now. But it's important to note this is not a complete list and rules are quickly changing. Travelers are encouraged to download the Smart Traveler Enrollment Program (STEP) from the Department of State to receive travel and emergency alerts.
