On June 11, the Central Epidemic Command Center (CECC) announced that strict border control measures will remain in force during the effective period of the nationwide Level 3 alert in order to alleviate the burden of the testing capacity and medical resources as the COVID-19 situation in Taiwan is not stable.

Border control measures are listed below.
A. Non-R.O.C. nationals without a valid Alien Resident Certificate (ARC) are temporarily barred from entry; exceptions may be made on a case-by-case basis for individuals who obtain entry permission for emergency or humanitarian reasons.
B. Transit travelers are temporarily barred from entry.
Those measures will be adjusted by the CECC on a rolling basis based on the status of the pandemic at home and abroad and the effectiveness of COVID-19 control measures implemented in the community.
