In this guide
What it means
A foreign broker may offer attractive access to global ETFs or stocks, but not always direct Swiss-market access or CHF-native workflows.
How to use it
The decision should be based on instruments, custody, documents, transfer path and how easily the investor can maintain records.
Investor checklist
Check accepted residency, base currency, FX conversion, tax reports, regulator, deposit rules, estate issues and support language.
Frequently asked questions
What should I remember?

The main risk is hidden friction around currency, tax records and support.
