The process of bank account opening in Switzerland begins with the correct assessment of the capabilities.
It is not worth starting the process if you do not have a permanent income, if this is your only savings or the amount you want to deposit at your account is less than CHF 100'000.
In most EU countries, the minimum amount of state deposit guarantee is just EUR 100'000. Considering that the cost of an account opening with a Swiss bank will be at least CHF 2-3'000 - this becomes impractical.
