It turns out there is a sufficient amount of immigration that is disliked by the populace that they will dump support for long-standing parties in favour of those who promise change.
In a sense, you may be correct, but who cares? The majority of people voted against xenophobia, some people are still super xenophobic and will continue to try to implement xenophobic policies, and the majority of people will keep voting against them.
This was widely understood to be a vote on how well the SVP can appeal to the center. Turns out pretty well but it's not entirely surprising given their recent election results.
So what will realistically happen, if we look at the trajectories of other countries, is that immigration will continue to rise, more people will be peaked by the discontent it can sow, and the popularity of this party will rise further.
There are valid and reasonable reasons to dislike large-scale immigration beyond supporting despots for the sake of doing so. The mainstream parties are not offering alternatives, can you blame those who are disaffected by this rapid societal change from reaching out to support the first name that voices critique at policies they dislike?

2. How long as a regular person without a job or special skills until i can be citizen?
3. How often do either of the two above happen?
