Re: Can I open a CH current account before I arrive?
Yeah you'll have the accounts same day with all the cards etc arriving in a few days (for Postfinance anyway). You won't get an overdraft though at Postfinance until you're C permit though... but a credit card is fine. :/
Oh also, I donno about other banks, but Postfinance has a limit of how much of your money you can spend each month. It's not that high a limit, something like 2k from memory (per debit card) and so it may be a good idea to increase it straightaway! I couldn't even conceive such a limit existing.
