Many overseas students think that they can boost their finance by working whilst they are studying.
Part-time and temporary jobs in the vacation are very difficult to find. Although it may be difficult for you to juggle coursework and a part-time job many international students do manage to make it work. However, in some cases it may be illegal for you to take employment. This can only be changed by an application to the Home Office. In all cases, the condition of entry to the UK shown on your passport should be checked before you seek employment.
