Hi - I plan to travel to Ireland in May for a week on a USA passport (tourist, no visa). But then I intend to take a train to Belfast, stay a night, then fly to Scotland to sightsee there & in England, before flying back to USA from London.
My question is: how do I meet up with UK customs in Belfast when arriving by train? I know there is no check at the border to Northern Ireland, but at some point I may need to show that my passport was stamped to enter the UK, so can I voluntarily choose to go through customs in Northern Ireland when arriving by train? If so, how/where do I go? Is customs available at Belfast's train station? Thank you!
