哈喽各位好，我下学期要来ETH交流 想问一下各位资金证明怎么弄 好像必须是在瑞士有分行的银行才可以办理 你们当时用的哪家银行。还要visa办下来要多久啊

我现在大四 建筑专业
老师发的邮件里说
Visiting students must produce evidence of sufficient financial means
to support their stay in Switzerland. You can do this by providing bank statements and/or scholarship awards. For bank statements: The Immigration Office requires confirmation from a bank with a branch in Switzerland (foreign bank with a branch in Switzerland or a Swiss bank). In the Canton of Zurich, as a rule, you must be able to provide evidence of having CHF 1'750 per month during your mobility studies, including the examination period at ETH Zurich. The account must be registered in your own name and the currency must be Swiss Francs, Euros or US Dollars. No other currencies are accepted! Supporting letters of parents are not accepted.
我的交流是从2-8月， 所以我卡里要有7*1750的法郎嘛 还是需要银行开一个我父母的工资证明？
求帮助！！！

父母工资证明不用貌似
