A friend of mine was trying to apply for a Czech tourist visa with his wife and two children. He had a letter from the school certifying that the school won't object to their absence. However, the VFS center refused to receive his application for the visa, stating that as a matter of policy the Czech consulate doesn't issue visas to children during the school year.
Are such restrictions legal according to Schengen rules? Could anything be done to force the consulate to process the application?
