I'm curious about the facilitated Swiss citizenship process for a Non-EU citizen, but without being in registered partnership nor marriage with a Swiss citizen. As a side-note, the job that person would work would be a high paying job in the IT industry.
There is this 'Article 22' that I found here, where it says the following:
Anyone who has lived in good faith for five years and has Swiss citizenship, and during which time has actually been treated as Swiss by cantonal or municipal authorities, can apply for easier naturalization.
What does 'good faith' mean and how can someone determine if a person 'has been treated as a Swiss by cantonal and municipal authorities'? Also, does that mean living for 5 years on a C-permit?
A few more paragraphs can be found here under the 'Irrtümlich angenommenes Schweizer Bürgerrecht' chapter.
I know many of these things vary between cantons, but I just wanted to make more sense by asking here as I'm not a native German speaker.
