Application for a British Ex Pat living in Valais Canton Switzerland

Hi Guys,

I am a British national living and working in Switzerland (with a B-Permit) year round. I will travel to China (Harbin) this year 23rd September. It will be a 7 day work trip and I already have a letter from my place of work over in China.

Can I apply online somewhere for a Visa in Switzerland or do I have to travel to Bern/Zurich to do it in person? If so do I need to book an appointment? Is there a form I can fill in before going perhaps?

Many thanks,

Tom
