Most European, North American, Gulf and East Asian visitors do not need a visa for a short business trip to the UK but must obtain a UK Electronic Travel Authorisation (GBP 16) before boarding, usually decided within three working days. Nationals of India, China, Pakistan, Nigeria, Turkey and much of Africa and Asia need a Standard Visitor Visa (GBP 127), which takes around three weeks and requires a biometric appointment. Irish citizens need no permission at all under the Common Travel Area. ATA Carnets are accepted for temporary imports of machinery, samples and stand equipment.
