There are different categories for Tier visa, but tier 1 visa application is unique since it will not require you a sponsor to back you up. The visa application will be done in a single process either submitted from outside the country or inside the country.

All applicants will have to submit different documents to support and would help to substantiate their tier 1 visa application. Approved tier one candidates may now enter the United Kingdom or make an extension of their stay if already inside the UK.

The Tier 1 is like previous HSMP or the Highly Skilled Migrant Programme which intends to facilitate possible relocation of skilled migrants who wished to enter United Kingdom. The points system would be basically the same but more accommodating to applicants.

The Tier 1 visa is the only tier that would not require or demand that an applicant must have a Certificate of Sponsorship in the UK’s migration structure. This Tier 1 is designed to attract people who fall under the most talented migrants’ category to come and work or live in UK - Economically beneficial to the UK government.

The documents that you need to submit must meet the standard of the UK visa processing or else, even if you are qualified for the Tier 1, you will face problems in getting the visa. Make sure that you have the right covering letter for Tier 1 visa in UK to explain clearly your intentions in coming to their country.
