Recommendations to learn Swiss German

Hi friends. I am a non-EU applicant who was recently admitted to the University of Zurich as a Master's student. I made the mistake of thinking that French was the language spoken here, so I learned the same, but a few days back I found out that the actual language spoken in Zurich specifically is German or rather Swiss German. So I wanted to know:

1) Do you have any reliable online sources for learning Swiss German specifically? I found German on Duolingo but no Swiss German (ironic when they even have High Valyrian as a language :( )

2) Is there any limitations in inter-canton travel imposed by a student visa? (I know this is most likely a question to ask the visa guys in my country, just wanted to know if you have heard or seen anything regarding this)

Thanks in advance for any help here!
