Visas - Entry Requirements

Citizens of the European Union do not need a visa to enter the United Kingdom, but do need to travel with their passport. Citizen cards will not be accepted. If you are from any other country out of the EU, find out about visa requirements before you travel by visiting http://ukvisas.gov.uk. If you require a visa, please contact conferences@iop.org. Please note that invitation letters will only be issued to delegates who have paid the registration fee.
