Alla de områden som du nämnde finns på den så kallade Vanligt reseområde ...
The Common Travel Area (CTA) is a travel zone that comprises Ireland, the United Kingdom, the Isle of Man, Jersey and Guernsey. In general, the CTA's internal borders are subject to minimal or non-existent border controls and can normally be crossed by British and Irish citizens with minimal identity documents.
The UK Border Force does not carry out routine immigration checks on travellers (regardless of nationality) arriving in the UK from another part of the CTA. However, because the Channel Islands are separate from the UK for customs purposes, it carries out selective customs checks on travellers arriving from there.
Så det finns inga andra kontroller än slumpmässiga kontroller.
Kontrollerna för personer som kommer från det gemensamma reseområdet till Irland med flyg eller hav har några formella arrangemang, men de är också till stor del slumpmässiga ...
In 1997, Ireland changed its immigration legislation to allow immigration officers to examine (i.e. request identity documents from) travellers arriving in the state from elsewhere in the CTA and to refuse them permission to land if they are not entitled to enter. Although this is stated to apply only to people other than Irish and British citizens, both of the latter groups are effectively covered as they may be required to produce identity documents to prove that they are entitled to the CTA arrangements.
OBS! Även om ankomster från Irländska republiken till Förenade kungariket inte är föremål för inspektion, finns det vissa villkor där personen blir en olaglig aktör.
