I'm a freelancer Software Engineer. When I talked to those agencies mentioned by the Embassy, they said I'll have to submit my company letterhead, trade license and visiting card, otherwise I won't get the visa. But as a freelancer I don't have those except my personal visiting card. By the way, I'm gonna get an invitation from the sponsor company.

I want your suggestion on this matter. What should I do in this situation?
