A Schengen visa sponsor letter – is written by a sponsor who does not necessarily have to live in one of the Schengen countries or accompanying the traveller to their trip. This can be a person who lives in i.e. the US, and wishes to sponsor the trip of the visa applicant to the Schengen Area. In this case, the sponsor will have to prove they have paid for the travel tickets, accommodation and daily expenses of the traveller.
