Delegates travelling from overseas should check the current UK entry requirements for their nationality before booking travel. Depending on nationality and circumstances, a visitor may need a Standard Visitor visa, an Electronic Travel Authorisation (ETA), or neither. Attending meetings, conferences and seminars can fall within permitted business activities for a Standard Visitor, subject to the applicable eligibility rules.
