Your visa letter is your acceptance letter or letter of admission offered to you by your sponsor in the UK (licensed education provider). This letter means that you have been admitted at some certain college or university.
This letter must be an official unconditional offer to you for the certain course of study.
The visa letter must be originally issued by the sponsor and must include original or electronic signature of the authorized official.
This letter cannot be issued by a representative. It contains some information about the applicant and it should not be older than 6 months.
You must present this letter with your application for your UK study visa as this letter earns you 30 points in the new TIER-4 POINTS BASED SYSTEM.
Remember, this letter is not the guarantee for your study visa. For your visa you need to fulfill all the visa requirements.
