Students who have got a place to study on a full-time basis at some form of educational institution may enter the UK as a student. Students are allowed to work on a part time basis roughly around 20 hrs an week which enables them to earn to meet their living expenses. However, those on student visas may work 20 hours a week during course term time and 40 hours a week during holidays.
Normally if the student will be studying longer than one year there are no restrictions for their spouse and children to work in the UK.
Candidates wishing to enter the UK on a student visa should make it clear to any immigration and visa officers that they intend to return 'home' at the end of their studies.
Candidates from visa-national countries (those who need a visa even for entry to the UK as a visitor) must apply for a student visa at the British Embassy/Consulate/High commission in their home country. Other candidates have the option of presenting the relevant documents to the Immigration Officer on entry, or may apply from within the UK to switch from another category to that of Student.
Student visas are normally granted for an initial period of one year, usually determined by the length of the course to be studied.
