Hi
My name is Khoi. Im from Vietnam and going to univerity in Geneva. Recenty i got accepted to transfer to Australia and im leaving by the end of Feb. I totally forgot that my B-permit expired since 12/2011 until i found out last week that i really need to go to Sweden before i leave. Im hoping there is some kind of temporary visitor or schengen visa i can apply for just to take 1 trip to sweden before i leave switzerland for good. If anyone have a solution for my situation please help me. Ive been trying to find a way to go but still no luck yet.
Thank you very much.

you need to call the Sweden embassy - they are in charge - not Switzerland

I am not sure. I think Switzerland can give D visa for this period. May be Sweden as well. But she can travel by train, there is no identity control, not by air transport.

This is risky: there is no systematic control but sometimes on trains they do unscheduled passport checks.
