How to receive a tourist visa after a residency permit in the Schengen zone
Well, when those residency permits end so does your right to be in the Schengen zone. While the bad news is that while you can’t change from a residency permit to a tourist visa from within the zone, the good news is that you can leave and return for fresh 90 day tourist C visas (on arrival entry stamps).
Typically, as you know, if you stay in the Schengen zone for 90 days on a tourist visa you have to stay on the outside for at least 91 days before returning, but this is different if you are on a residency permit and then leave and return for a tourist visa. Though I would not recommend doing a mass visa run with 70 people, as what I am telling you may be a bit of a grey area in the rules.
Keep in mind that this generally works, but there are different interpretations of the Schengen rules by the various immigration bodies that are set up to enforce them. With 25 countries all enforcing the rules slightly differently many travelers have been caught in the gaps of interpretation, so to speak. I would recommend not exiting the region through Germany, Switzerland, the Netherlands, or any Scandinavian country when finally leaving the Schengen region after your tourist visas are up. Italy and France tend to be the laxest with their interpretation of Schengen immigration law.
This is the best that I can help. If you could report back and let me know how everything works out for you and your crew then I could better pass on the word to other travelers. Thanks!

Complete question about receiving a tourist visa after a residency permit in the Schengen zone
About 70 teachers in Hungary, most of us from the US. We have residency permits (usually for 1 or 2 years) that expire during the summer after school is over. How can we legally stay on and travel for a bit afterwards without running afoul of the Schengen authorities?
