Under tier 2, a migrant has the right to work in the UK for a maximum of three years, what happens when this period expires?
Tier 2 gives an initial grant to work in the UK for three years and employers issue a certificate of sponsorship (CoS) to cover this period. When the initial period expires the employer can apply for a CoS for a further two years and the individual will need to apply for an extension to their leave to remain.
