Tier 1 of the new points-based system being introduced on a rollout basis by the Home Office will commence on 29 February 2008. Tier 1 of the system, which caters for Generally Highly Skilled Migrants such as scientists or entrepreneurs, replaces the current Highly Skilled Migrant Programme (HSMP). Unlike applicants in Tiers 2 to 4, Tier 1 applicants are not required to have a job offer or sponsorship from an employer. For those that can score the required points under this system, this is likely to be the preferred route of entry into the UK. While there are a few differences between the current HSMP and the new Tier 1 generally highly skilled migrants subcategory, probably the most significant change will be the increase in fees. The government has announced that fees for first-time highly skilled migrant immigration visa approvals are to rise from £400 to £600 in the near future.
