The Ordinance on fees under the Federal Act on Foreign Nationals (SR 142.209) and the Visa Code stipulate the fees to be collected. The amounts are payable in the currency determined by the Swiss representation.
The fee for the visa is due at the time the application is submitted and is not refundable. If you withdraw the application or it is rejected the fee will not be reimbursed. From 26 March 2018 it is also possible to make payments online while filling the application form.
The Swiss representation reserves the right to adapt the amounts of the fees at any time in relation with exchange rate fluctuations.
