Hi, I am an EU citizen with wife from a non-EU country (one which does not require any visa to visit Switzerland.)
I have got a B permit and stable job here, so I would like to know what procedure would be good to follow for my wife to join me here as a dependant.

I have visited the Kresiburo and they told me “no problem, just come here and register after she arrives in Zurich”
I guess that would be OK for the Kreisburo, but the issue is with immigration and entry into the country.

I tried asking the Zurich migrationsamt and got 4 different responses so far
1/ you need to register on our website and apply for permission before coming
(I looked on the website but the it was not clear how to apply or what to apply for)
2/ you can come on a short stay, but need to go back to original country to apply for permission to come long-term
3/ you can come and you should register as soon as you arrive
4/ you can come but make sure to register before your 3-month stay period ends

It may sound confused, but it would be nice to have a definitive answer from someone who has had the experience to say or could advise me, as I could not get that so far from the “authorities”. I guess it comes down to a choice between either
A/ Just come anyway and change from short stay to dependant B-permit or
B/ Apply for permission to come before entering the country
