If in your first visit with the bank you do not convince to open an account, you will become part of a blacklist that will be shared secretly within the other banks and you will have the vetoed entry to the paractical totality of the banks. A simple mistake during the KYC questioning will catapult you directly to the blacklist. This is how they work in CH although this is not public or notorious. The simple fact of saying that you live in a country (with prooves like utility bills) and giving a contact phone or a detour from another country to︀ receive mail is more than enough to be blacklisted. Useless re-enter any other branch of︁ the bank. Very complicated open account in CH. You must to contact previously by email︂ with full name, address and phone number. If they do not answer the email, (which︃ is the most provable in 60% of cases), you have to call them by phone︄ to ask if they have received the email. Then they will see if your call︅ corresponds to what you say you have written. They will answer you and tell you︆ to send them information about what you are looking for and who you are (︇ copy passport, residence proof, etc.., When you send all this, you will have to take︈ an appointment and go to visit them personally taking with you all the proof of︉ the money you want to enter. After a few weeks or months they will contact︊ you to tell you if they accept your case or not. In the interrogation of︋ the KYC take a prostate ecography in case you are asked. 😉 Tetal bank don'tinterest them︌ because each no swiss resident account it's a big cost for the bank
