As of July 19, U.S. visitors who have been vaccinated, have a negative PCR test within 72 hours of arrival or have recovered from COVID-19 in the last six months will be able to visit Ireland and they will not have to quarantine.
Ireland will be following the advice of the European Union, which, earlier in June, suggested to its member states reopen to select countries, including the United States, subject to confirmation of reciprocity. While the United States has not yet officially opened its borders to Europeans, many E.U. members have announced plans to reopen to Americans, if they have not already reopened entirely.
Travelers to Ireland will need to use the E.U. Digital COVID Certificate (in either digital or paper format), proving they have been vaccinated, received a recent negative test result or have recovered from COVID in the last half-year. Your certificate will include necessary information, such as your name, date of birth, date or issue, vaccine/test/recovery history and an ID number.
Ireland plans to launch the certificate when it reopens on July 19. According to the Government of Ireland, “Teams across the public service are working together to deliver the E.U. Digital COVID Certificate in Ireland and you will be clearly notified of the steps needed to access the E.U. Digital COVID Certificate soon.” So, be sure to keep an eye out for updates before traveling.
Note: Americans can currently visit Ireland, although there is a mandatory 14-day quarantine (with few exceptions and none for tourist reasons). They still need a negative PCR test result from within 72 hours of travel, fill out a COVID-19 Passenger Locator Form and take another test upon arrival free of charge.
