Can you inform me what kind of Visa and documents do I need?

Hi, you should apply for a Z type. The documents you will be required for submission include: a passport valid for at least six months and having two or more blank pages, a copy of the passport’s photo page, a filled-out application form attached with your recently-taken passport type photo, and a work permit and invitation letter from Duly Authorized Unit which can be obtained with the help of your employer.
