Foreign Nationals Foreign Nationals travelling to Iran are required to present at the port of entry (POE) a negative Covid-19 (PCR) test result in English (approved by the Iranian Embassy, if in local language) taken maximum 96 hours before arrival. Failure to do so would result in the return of passengers to the ports of departure. In case of expiry of 96- hour validity of the test results passengers will be screened at the port of entry and a new test will be taken of anyone displaying symptoms of Covid-19. The tested individuals will be quarantined in a specified location until the test results are out. 14-day quarantine will be mandatory for those with positive Covid-19 test results. All costs relating to tests, accommodation and upkeep will be borne by the passengers   Iranian Nationals Iranian nationals returning to the country after an absence of more than 2 weeks will be required to present a negative Covid-19 (PCR) test result in English (approved by the Iranian Embassy, if in local language). In case, and for justifiable reasons attested by the Iranian Embassy, it is impossible to obtain a PCR test in the country or territory of departure, airlines can conditionally allow Iran-bound passengers to board. These passengers will, however, immediately upon arrival, and without regard to clinical symptoms, undergo a Covid-19 test. They will be required to give written guarantees for self-isolation until test results are known and those with positive test results or symptoms of the disease will be subjected to a further 14-day self-isolation. Costs of tests and possible quarantine will be borne by the passengers.   Diplomats and International Agencies   Diplomats, political delegates, and employees of international agencies (based on act of reciprocity) will NOT be required to present test results but will be screened upon arrival. A test will be taken of those displaying symptoms of Covid-19. The tested individuals will be required to leave a contact telephone number and a letter guaranteeing to self-isolate at their local Embassy or specified locations until test results are out and in case of a positive test result, spend 14 days in quarantine.  General All Iranian and foreign nationals (even with certificates of negative test results) will be screened upon arrival. Health service procedures will be followed for individuals with Covid-19 symptoms at specified medical and diagnostic centres. All passengers entering the country will be required to present completed self-declaration forms obtained from the airline during or before flight. The airline, if requested by the border health authorities, is required to make available the passenger list and self-declaration forms.   All passengers leaving the country must be screened at a health service centre or at the airport. A health certificate will be issued if required by the destination country.   The international situation is very closely being monitored and this advice will be under constant review.
