Is it permissible to keep one's salary in a Riba-based bank in a country where no Islamic bank exists, in order to avoid the exorbitant transfer fees to an Islamic bank in another country?

If there is no Islamic bank, there is no objection to the salary being deposited in a usurious bank in a current account that yields no interest. It is preferable to withdraw the salary quickly so that the bank does not benefit from it in illicit activities. There is no need to expend large sums to transfer the salary to a bank outside the country.
