Recently i went to the uk and i have my uk c child visit tourist visa i went to the uk alone but when i reach the uk the officer denied my entry because when he called my hotel they told the officer that we cannot accept 17 year old alone i didn't checked the hotel policy so that was my mistake but he told me to book a hotel at that time but i didn't find any hotel accepting a 17 year old alone after that he told me to book a return flight and i booked my return flight and after that he just wrote elected to embark 23/04/24 on my passport and handed my passport to me they didn't did any paperwork in front of me and they didn't give a single paper to me they just checked my visa and every after that they just leaved me at transit area and i don't think they did any documentation because they didn't give any paper so is my visa cancelled or my visa is okay please tell me what does elected to embark mean is it good because i think the officer tries to help please i was worried about my visa please help me ?what do you think about my situation ?
