This is passive-aggresive level 1’000, probably mental illness.
Someone is sending letter pretending to be the Migration Office of Switzerland telling people their residence permit is cancelled.
First question that comes up is: WHY?
This is only about upsetting people for a few minutes or hours, because anyone would contact SEM to confirm this and find out is fake. No one will leave Switzerland because a stupid letter.
It explains later:
Creating a regime of fear is the start of it manifesting itself openly.
A nutter that seems to have addresses of people and whether they are foreigners with B/C permits rather than naturalised Swiss. Data leak?
Phone books still publish addresses. It wouldn’t be too difficult to guess who isn’t Swiss from the surname alone.
Not necessarily a data leak.
Edited to add: Just went to Local.CH and searched for postal code and name of our village. I got just about everyone in the village’s name and address.
I’ve been once watching a YT vlog on privacy in Switzerland and the author was basically encouraging to pro-actively hide the following info:
As for the latter two points I did not fact check them, as for the first one I indeed had to block license plates in the registry in Vaud.
Is there any way of figuring out if they are on a B or C permit? The article seems to suggest the letters were close enough to convince recipients they were real.
Not from that source, other than guessing based on surname. Take mine, for example. It is not typically Swiss.
People working in the police or communal or cantonal government likely could have access to the permit status. At one time this information wasn’t easily obtained on a large scale but with digital permits it could be just a few keystrokes away.
This for example Data leak at Xplain: SEM also affected
Lol, for this kind of people (crazy) whether you’re naturalised or not doesn’t play any role. But do you think they’ll say “Oh look at this nice auslander, now he’s Swiss so it’s a good one now.” These people don’t function like that. (it’s nothing rational here)
It’s a hate scam if it makes any sense, they most probably just chose random people to send that piece of misery.
While such letter is certainly disturbing I wouldn’t leave even if it came from SEM but appeal at European court. Switzerland is strongly bound by bilateral agreements so has to respect freedom of movement. Expelling an EU person from Switzerland is really hard. One would have to commit a serious crime with a court conviction to justify it, etc.
There is certainly a percentage of the Swiss population that would prefer to cut ties with the EU. But until they can convince the majority of the population, their only “small victory” is to lobby locally to discriminate against EU people in employment decisions, so that they end up leaving for economic reasons or not coming here at all. I can certainly name a few people who do this from my current and past surroundings. I guess you will see such people in your organization if you are anyhow involved in hiring.
Expelling anyone is really hard, you might be surprised to know that. And I am willing to bet there are way more non-EU residents the Swiss would gladly get rid of, if they could.
You too can do that, anyone can do that.
The alleged violation of your rights must have been committed by one of the states bound by the Convention.
Some years ago I received a phone call (land line, no number recognition). The mature caller spoke Swiss German and claimed to be from the Cantonal Police and it was his duty to warn foreigners that they could be in danger,
I asked for his phone number to call him back for verification. His response was that it was in the book. I then spoke English say that as it was his job to advise foreigners of possible danger, his English must be very good.
Silence, then he hung up…
Wow some psychos are really taking it to another level, I wonder if such attitudes towards foreigners are more prevalent in the German-speaking part?
I think it’s the passive-aggressive post-it taken to the next level.
Someone in my apartment building has been leaving anonymous messages about not smoking. I’ve never smelled cigarette smoke in the underground parking, cellar or the elevator/stairs cube. Anyway, someone with lots of free time gets some joy from leaving these messages.
So it looks like the messages worked.
What a coincidence.
A guy in custody of the ZH police has been linked to fake dismissal letters sent to bank and business managers in AG and ZH. The same idea, an idiotic letter telling people “you’re fired”.
Maybe they have an undiagnosed brain tumour? Don’t you start to imagine the smell of burnt stuff as a symptom…? 
One of my OH’s colleagues used to come home from work only to find notes on post-its on his door, with insults and the imperative to “move back to their country” (funnily enough, the author thought that a political region is one big homogenous country) and knew who could that be but never took any actions. Both him and his wife were usually coming late from work and it didn’t really bother them. They moved from that building (cheap rent, eh) only when they bought their own apartment (and ironically, after that old guy moved from there). They were the only ones who got these “love letters” for reasons unknown to this day. (didn’t party, didn’t have visitors, didn’t listen to loud music, didn’t smoke, didn’t have pets and kids at that time AND recycled properly)
If it helps: this is NOT a Swiss official position, just some weirdos out there.
At times I am feeling like it could be not even Swiss doing that but long term residents or new Swiss at best…
Who knows, right?
