Preferably, the reference letter should be printed on the company’s letterhead, which is represented by the recommender. It is important to describe how and how long you have been acquainted, the real facts of your professional achievements, and why the recommender considers you a worthy candidate for a Global Talent visa. It is important not to praise yourself, but at the same time not to diminish the merits, so that the commission sees your real value as a specialist.
