a passport stamp, regardless of whether they use an ePassport gate or a staffed counter. However, citizens of these countries who enter the UK with a Tier 5 (Temporary Worker – Creative and Sporting) Certificate of Sponsorship (for up to 3 months) or on a permitted paid engagement are not eligible to use the ePassport gates and must use a staffed counter, where they will receive a passport stamp. When the transition period of the UK's withdrawal from the EU came to an end on 31 December 2020, EU, EEA and Swiss citizens became subject to immigration control. However, regardless of whether they hold settled or pre-settled status under the EU Settlement Scheme in the UK, EU, EEA and Swiss citizens continue not to receive a stamp when entering the UK on their passport or national identity card. In the case of general aviation flights arriving in the UK from outside the Common Travel Area, travellers may not be inspected by the UK Border Force on arrival (depending on the risk assessment conducted on the basis of the travellers' information submitted in advance via the General Aviation Report (GAR) form) and may be 'remotely cleared' instead. In this case, no passport stamp is received. Previously, all travellers entering the UK using the Iris Recognition Immigration System (including non-UK/EU/EEA/Swiss citizens) did not receive a passport stamp. The UK Border Agency had a policy from 23 June 2008 until 4 November 2011 of conducting onboard clearance of some passengers travelling by coach at the juxtaposed controls at the Port of Calais and the Eurotunnel Calais Terminal. Passengers' travel documents were visually inspected by a UKBA officer on the coach, without the passengers having to disembark and pass through immigration control (where their travel documents would be scanned and, when required, stamped). This concession mainly applied to school groups travelling within the European Economic Area, though it was also extended to some other groups, such as elderly passengers, travellers with special needs, brownie and scout groups and sports teams. This policy meant that some passengers whose travel documents would usually be stamped did not receive a stamp on entering the UK.

Accordingly, no passport stamp is received. There are no routine exit
