Consider this case:
A US-citizan has overstayed her SCHENGEN-VISA in Austria. She realized when she travelled outside the Schengenzone. She does not want to wait 180 days but she wants to return to Schengen much sooner, to Hungary, to invest into a business there, like a opening a bar or restaurant. Is there a way to get a business or special VISA granted exclusively for Hungary or any other alternatives to waiting out mandatory 180 day period?
