If you want to come to the UK as a tourist or to visit friends you should apply as a general visitor. A visitor is someone who generally intends to be in the UK for a short period, for example, to visit friends and family, to do business, to do a short course of study, to have private medical treatment.
If you are employed abroad but want to visit the UK for short periods to undertake business related activities you may be eligible to do so as a business visitor. Other categories include student visitors, entertainers, sports visitors, people seeking medical treatmentand other special visitors.
Visitors can stay in the UK for a maximum of six months at any one time. A general visit, business, entertainer or sports visit visa may be valid for 1, 2, 5 or 10 years.
The Ancestry visa allows a Commonwealth citizen, aged 17 or over, to immigrate to the UK with the freedom to live and work in Britain on the basis of their ancestral ties to the United Kingdom. They must have a grandparent who was born in the United Kingdom, Channel Islands, or the Isle of Man.
Applicants coming to live and work in the UK under this route must intend to seek and undertake employment and must be able to support and accommodate themselves without recourse to public funds.
This immigration route is intended as a route to settlement. The ancestral visa is granted for five years after which applicants may apply for permanent resident status. Beyond this, subject to meeting the appropriate requirements, an applicant may be able to apply to become a UK citizen through British naturalization.
Dependants of applicants will be eligible to apply for an Ancestry Dependency visa.
