Expedited processing of the visa application for a number of countries will usually incur extra charges. If you would like to stay in each Schengen country for exactly the same length of time, you must submit an application for a Schengen visa at the mission of the very first Schengen country you plan to go to. Visas are related to the request for permission to go into a nation and thus are, in some nations, distinct from actual formal permission for an alien to enter and stay in the nation.
