in U.K., how to prepare CV
Occasionally people entering on UK ancestry or other visas (like fiancé or marriage) have been granted entry subject to medical examination. It isn't uncommon to be X-rayed at Heathrow for tuberculosis!
If you travel on a holiday visa, it is also recommended not to pack your CV, references, work clothes, tools or anything else that may lead to further questioning. Many people prefer to mail them ahead, or you can send an e-mail to yourself and pick it up when in London. If you have a lot of documents, you can use (Free "Hard Drive storage!!!) at WWW.FREEDRIVE.COM. Sometimes carrying a book like "Working your way across Europe" could arouse unwarranted suspicion, so keep this in mind. Immigration officials have also been known to search belongings, and read address books, call your friends and contacts, open personal sealed letters, and diaries! Even though you may be allowed to work on certain visas, your intentions to find particular work may be misconstrued and your entry disallowed.
