To visit Maldives, you just need a Negative COVID-19 test report within 96 hours before departure. You can submit that report online.
The negative Covid-19 PCR test result must be attached while completing Traveller Health Declaration form, which has to be submitted online by all arriving passengers prior to arrival (but not exceeding 24 hours before arrival time), via IMUGA (www.imuga.immigration.gov.mv).
