In the Immigration Rules an `amateur’ is defined, for the purpose of distinguishing him from a professional who is paid a salary for participation in a creative activity,  as a person who engages in a creative activity solely for personal enjoyment and who is not intending to derive a living, either wholly or in part, from it.   For practical purposes both amateur and professional entertainers may enter as entertainer visitors in the circumstances set out above.  Amateurs may not receive fees and sponsorship but may receive cash prizes as well as board, lodging and living expenses.
