With the Highly Skilled Migrant Program (HSMP), you can work as a self employed contractor.

In the UK, contractors earn a lot more compared to their permanent full time employed counterparts.

For example the best way to approach the UK IT contract market will be to start with short term contracts. Once you get a few short term contracts under your belt you will be in a very good position to apply for a permanent post.

HSMP is a must have for contractors . Provided you score at least 75 points, you can apply yourself, then start looking for a job in the UK as contractor. There are significant advantages to HSMP compared to a Work permit. After 5 years as an HSMP holder you can apply for Indefinite Leave to Remain (Permanent Residency) and after 1 more year you can apply for British Citizenship (naturalization).
