(Fatwa: 606/599/N=07/1436)
If you have not to deal the interest based dealings in the bank where you want to work for Foreign Exchange and the owner of the bank is Muslim or it is an Islamic country and your salary will not be paid from the interest amount then you may work in the Foreign Exchange department of the bank. As the currency of two different countries are treated as separate kind and it is lawful to exchange them with difference with mutual consent provided one exchange is taken into custody in the meeting of transaction.
Allah knows Best!
