Following on from this thread, I thought it worth putting together a list of things that need to be done once you complete that process.

Feel free to add to it:

• Inform your employer
• Inform any insurances (especially car, it may get cheaper)
• Inform drivers licence/car ID authority (get new grey card & licence)

Do you need to:

• ...

You don't need to:

• Inform health insurance

Feel free to add to this, if I can amend this first post, I will.

Your Auto insurer, Swiss citizens get better rates.

Driver's license. It lists your place of origin, which is now in CH.

I didn't.

Maybe it depends on the canton.

I think that I only informed the DMV.

Carte gris too.

When you visit they might want to renew your DL photo so bring one with you.

If you are close to a vote you should remind your commune, they have to do something special to ensure you get your voting papers.

I think it was the insurance company. They very carefully explained that they did not give a discount to the Swiss, they only charged non-Swiss more.

Great idea, thanks for creating this thread.

I just wanted to post that I called the Canton Zurich road traffic office (Strassenverkehrsamt Zurich) asking about the procedure to update the driver's license. They just told me to keep a copy of the existing driver's license with me and send the original with a copy of the new Swiss ID to their office and they would update it.

And send you a bill for doing so.

Is it mandatory to change the details on the driving license if you still retain the previous nationality as well?

Just called the Strassenverkehrsamt, they said it is not mandatory.

Called the health insurance, they said that there is no meaning in informing them about the naturalization as they don’t use this information for anything.

Strassenverkehrsamt sent already the updated driving licenses: 1 day to process my request.

I assume that also included an invoice for the change?

Hopefully I'll be in this situation next year, but I don't have any desire to pay a bunch of unnecessary 50 CHF fees just to get "CH" instead of "UK" on some documents.

No invoice so far. There is certainly no free meal. I will publish the amount when this it arrives.

It’s the Commune of Origin and Canton that is added, not the country.

Thanks for the info.

I still don't feel any great need to have anything other than my identity card say this though, even if I get a bit more than two characters for my 50 CHF

In my case :
- University
- Bank
- Swisscom

Given that the UK will officially be non-EU very soon you might want to double-check which documents would be more useful with a CH as opposed to UK on them.

Your nationality is basically part of your identity. So you need to let everybody know who demanded to know about your nationality. Landlord, employer, all insurers etc.

If you are Swiss you can not live here, claiming you're something else. The Swiss is the main and only one that counts. As soon as you leave Switzerland of course you can chose, which nationality you want to give if you have several.
Not sure how it will be in your original country if you still hold it's passport. Probably the same?

As promised: CHF 15 to update 2 driver's licenses (my wife's and mine)
