I am a UK citizen and full passport holder since birth. I now live full time outside of the UK, each time I visit the UK, my passport is rejected by the electronic passport gates and I am routed to a human. Even when passing thru the human checkpoints something flags up on their computer and they park me in a little waiting area, go off and speak with a supervisor (or someone) and come back confused about the process (i.e. they have started filling out some documentation, before their supervisor advises them they should not be doing this process with a UK citizen), and ask me a series of questions (why I am travelling, where I am staying etc.) they don't seem to ever have a record that I am living outside of the UK and they ask me for residence information each time. After begrudgingly sharing them my reasons for travel and residence infos they always permit me entry.
Last time the border officer said they would submit a request to the home office to avoid me getting flagged each time, and I shared a mobile phone number for them to contact me regarding this (which they never have).
I am getting fed up of the hours long process each and every time I try to visit family in the UK, and honestly it puts me off traveling there all together. As a UK citizen they have no legal basis to deny my entry, am I under any obligation to answer any of their questions and what can they do if I refuse to answer further questions? How do I get this resolved, do I need to get a lawyer involved.
Should add that this is over a 2-year process this is happening, and I am not (knowingly) on any Interpol lists or anything like this 😁 I don't have issues traveling anywhere else in the world, only thru the UK border.
