This is about my most recent visit to the UK to spend time with my wife there until we can live together permanently.
The flight itself on United was ok, just ok, not great. They didn't have enough blankets to go around for everyone, so some of us had to stay cold. we landed at Heathrow airport a little early and went to passport control with no qeue ahead of our flight, so it went quickly. I got up to the immigration officer and she looked at my passport asked me questions, and then took my passort off me, handed me a sheet of paper saying why I was being detained and had me sit down. I was probably there for an hour before someone came back to take me to get my bags from baggage claim. Then he took me into a room and had me put them on a table so he could dig through them for "documents" (what he said he was looking for). He even counted my cash. Then he took me into another room where he took my picture, got my fingerprints and put me in the system. After that he led me down to a holding area where he locked up my bags in a separate room and I was kept there for the rest of my time of being detained. The guard down there patted me down and kept an eye on me through CCTV. I wasn't allowed to have my cellphone in there (no pictures were allowed) but there was a payphone in there so I got some change off the guard and rang my wife to let her know I was ok and what was going on. She had been waiting for me since my flight arrived. Immigration had even talked to her asking her a bunch of questions as well! Then another immigration officer took me into an interrogation room where she asked me a series of questions abut my purpose for being there and wrote down what she asked and my answers all in my file. She told me her colleague wasn't convinced I was going to leave when I said I was going to leave and they wanted to establish my purpose for being in the country. I told them the same thing at every turn, that I was just there for 2 weeks and at the end of that I was returning to the US. They kept me down in the detainment area for awhile longer (I tihnk Loose Women was on the TV down there) and she came back in and told me she talked with the immigration supervisor and had to convince him to let me enter the country, but on the stipulation that I was to leave at the end of my 2 weeks, not the 6 months that the passport stamp says and what is normally allowed for US citizens to do. I hadn't done anything wrong, hadn't broken the law in any way, and yet I was treated like a virtual criminal! My flight got in a little after 8 in the morning, and I was finally released about 1:30 in the afternoon. I was, for all intents and purposes, a Detainee of the UK for 5 hours. Being held without charge, having committed no crime.
