Ireland does not mandate a quarantine based on nationality. Any traveler arriving to Ireland from the United States is strongly advised to self-isolate for 14 days on arrival and is required to complete a COVID-19 Passenger Locator Form indicating where they will self-isolate. Failure to complete the form or providing false or misleading information is an offense under Irish law, with a fine of up to €2,500 (nearly $3,000) and/or imprisonment of up to 6 months.
A person arriving into Ireland without a negative PCR test faces a fine of €2,500 or six months in jail. There are no health screening procedures in place at the airports and other ports of entry.
