Why not ask the Polish Consulate in Bern if they can help.

All the best, R.

Thanks for your advice Ritchie. I asked the Swiss consulate in London and they didn't help. I'm not sure how a Polish consulate would know about the British procedures? I was hoping to get an answer from someone who's moved from one country to another. But thank you.

Nothing ventured, nothing gained.

Hi Kat,

Not all municipal offices ask for such a document, see e.g. Zurich https://www.stadt-zuerich.ch/prd/de/index/bevoelkerungsamt/umziehenmelden/zuzug.html.

Probably a personal visit to the desk of the municipality where you live would allow you to explain.

Best regards,

Andre

Hi André, thank you for your comment. I've seen online that a deregistration document is needed already at the border when moving personal belongings from abroad. A lady from the Uri kanton immigration office didn't really know what my enquiry was about. So indeed, not every municipality needs it apparently. But what about the border control? And still, I don't know where to obtain it. No office in the UK I've got in touch so far understood what I wanted from them.

Are you crossing the border into Switzerland by car?  If so, perhaps the Touring Club Suisse might be able to give some advice/guidance.

Best, R.

Thank you, I will ask there too!

Hi Kat,

I suggest you contacting the Federal Office for Customs and Border Securitywith your question directly by means of the contact form https://www.kontakt-formular.bazg.admin.ch/home. Probably you can even do it in English.

Best regards,

Andre

Hello André,

Thank you for the advice. I'll keep the link. I keep asking whenever I can as I've just found out recently, people who ever moved from the UK never had any document of this kind. What they had when moving was an Anmeldung from the Gemeinde in Switzerland. So it looks like I probably couldn't move with my goods right away as first I'd need to be "angemeldet". Even if it wasn't this case, it's okay for me as my stuff is going to arrive first when I've more or less settled. I've been advised to talk to someone from the local Gemeinde and not immigration offices. Not sure whether these institutions are connected or acting independently but for now I've got my answer. Thank you nevertheless for trying to help. That's much appreciated! :)))
