Course-focused and comprehensive, the Textbook on series provides an accessible overview of the key areas on the law curriculum. This chapter discusses the law relating to individuals coming to the UK as visitors for short-term or finite purposes such as tourism, business visits, sporting and entertainment engagements, or for private medical treatment. There is a discussion of the withdrawal, reinstatement, and restriction of rights of appeal for those visiting family members in the UK, and the application of Article 8 ECHR to these situations. The revised visitor rules in Appendix V are described in detail. The chapter also discusses the special cases of marriage visitors, carers and transit visitors, and general conditions such as prohibited activities and the need for maintenance and accommodation.
