Moldova has restricted entry to most foreign travelers. Travelers who have been in or transited through Albania, Andorra, Brazil, Czechia, Estonia, France, Hungary, Israel, Italy, Latvia, Luxembourg, Malta, Monaco, Montenegro, Netherlands, Peru, Portugal, San Marino, Serbia, Slovakia, Slovenia, Spain, Sweden, USA or UAE in the past 14 days are not allowed to enter. Moldova's border only permits foreigners if they meet one of the following exceptions: immediate family members of Moldovan citizens; persons having a visa, residency permit, or other document issued by Moldovan authorities; persons traveling for "professional interest" in possession of a visa, residency permit, or other document issued by Moldovan authorities; diplomats accredited to Moldova and members of international organizations and their family members; personnel who can provide humanitarian aid; passengers in transit. Transiting a red zone country could result in denial of entry into Moldova. As of June 30, other categories of people are allowed to enter Moldova. These include: people with a business visit visa, long-stay visa, residence permit or equivalent document, members and dependents of diplomatic missions, consular Posts and international organizations accredited in Moldova, personnel providing humanitarian aid, passengers in transit, people traveling for health and humanitarian reasons, cross-border workers, and drivers and service personnel, for the purpose of transportation of goods (aircraft, ship and train crew).Entry requirements
All travelers must complete an epidemiological questionnaire ("fisa epidemiologica") at airports and other ports of entry when entering Moldova and sign a statement that they will self-isolate for 14 days. Travelers must present a medical certificate with a negative COVID-19 PCR test result issued within 72 hours prior to departure. Children under the age of 5, passengers in transit, and holders of vaccine certificates are exempt from testing requirements. Moldova will admit foreign nationals coming from red zone countries if they are in possession of documentation demonstrating that they have received a COVID-19 vaccine.Quarantine requirements
Travelers from certain "red zone" countries are subject to a 14-day self-isolation, with exceptions including asymptomatic individuals delivering goods, crew members, students, people traveling for health care, work related travelers with visas, diplomatic corps accredited in Moldova, and passengers in transit. The Ministry of Health will update the list of countries on the red zone list every 2 weeks. Moldovan citizens without a medical certificate with a negative COVID-19 PCR test result issued within 72 hours prior to departure will be required to quarantine for 14 days upon arrival, regardless of the country from which they traveled.
