Work Study Visa
British nationals require visas to enter the mainland of China, but not Hong Kong. Visas must be obtained prior to arrival.
Your passport should have a minimum validity of six months on arrival in China. If you intend to stay longer than one year, a minimum validity of 18 months is required.
If you are entering China for employment, study or private purposes for a stay of over six months, you must produce a health certificate, which includes a blood test for HIV, which has been legalised by the Chinese Embassy.
