Onward Tickets from London to Buenos Aires

Do I need an onward ticket to enter United Kingdom?

If you’re from a non-EEA country

• Your carrier will give you a landing card - fill this in before you arrive at border control.
• Your passport, landing card (and visa if you have one) will be checked.
• You’ll usually be asked why you’re coming to the UK.
• Keep documents that show the reason for your visit in your hand luggage, so you can show them if asked, for example your travel itinerary, work permit or university letter.
