To,
The visa officers of the embassy.

I have already visited Schengen states last August, 2008 & at this time I want a go for business purpose so please confirm me which kind of documents I required form my counter part?

Invitation letter is attested any department or Simple Invitation letter & hotel booking is enough for you? If I required a attested so please mention the name of department & how many days you required for decision?

Best regards,
