There will be one representative of Rostest (not two like we previously informed).
The representative needs an original of Letter of invitation from MCP or KYE, stating that you (the factory) invite him to conduct certification works and take all expense on you (although we – MER – will pay for this). In the attachment you may find the passport – you should mention name, surname and passport no in the letter. Also he will need hotel booking confirmation to apply for visa.
