A visa should be asked for at least one or two months before a trip.
You can apply for both types of Norfolk Island visas and choose between plans for a single entry or plans for multiple entries.
Depending on which consulate we need to send the application to, it usually takes anywhere from 2 to 15+ days for the Norfolk Island Embassy/Consulate to process a visa. The time it takes to get a visa depends on a number of things and can be changed at any time by the consulate.
