The Finnish Border Guard investigates each passenger’s fulfilment of the entry conditions during their border check. If the conditions are not met, the traveller will receive an appealable administrative decision refusing them entry under the Schengen Borders Code. In most cases, the decision can be enforced immediately despite any appeal. After the passenger has been notified of the decision, the airline that transported them to Finland is obliged to transport them either back to the country of origin or to a third country to which they are guaranteed entry.
