So this wknd has been a very interesting one for my friend. Thought I'd share because honestly I have no idea why this occurred. She is from the Bay area, (Cali) who went on a work visa to Australia for 1 year. Her work visa expired over the summer and her plan was to travel around the world until her funds were gone. and then head home afterwards So she decided to goto various SE. Asian countries (Thailand/Laos/Cambodia/Vietnam/Indo/Malay), and I actually met up with her in Krabi in January. After SE Asia she went to Seoul to meet up with other friends. Last week she decided to goto London/UK and she booked an Aeroflot flight from Seoul to LHR. And now the funny thing, while @ immigration in LHR, she said they asked her a bunch of questions. I asked what kind and it sounded the usual ... where you staying, when you leaving, what ya doing here etc etc. Since she's been backpacking she said she was staying @ a hostel (that wasnt booked yet) or a friend's house & that she wasnt sure when she was leaving. She was just traveling the world. Then they asked her how much money she had on hand, etc & eventually they said she wasnt allowed into the UK. (At this point I was shocked & had a wtf look on my face.) UK immigration stated that since she was a US Citizen, she would need to go back to the US because that's the only place for sure that they'll accept her and she had a choice. Either pay cash to fly LHR - SFO; or wait and they'll force Aeroflot to fly LHR - SVO - LAX her for free. She choose the later & I went and picked up her at LAX on Friday. Sorry for the long post, but ... now comes my question. Why? How? I mean US/UK are pretty much in bed with each other, and I've never heard of this before. My thoughts ranged from they suspected she was a drug mule, a fugitive, attempting illegal immigration, and even a traveling prostitute... Can anyone shed some insight on this?
