The UK has launched an Electronic Travel Authorisation (ETA) scheme. This is a new requirement that grants visitors permission to travel to the UK, including Northern Ireland, and also to travel to Northern Ireland from the Republic of Ireland.
The ETA will be mandatory for everyone arriving into - or travelling through - the UK, including Northern Ireland, who do not need a visa. It is electronically linked to your passport, and will be valid for two years. All passengers must have one, including babies and children.
You don't need an ETA if you're a British or Irish citizen.
