Normally, working for a usurious bank is prohibited. This is endorsed by the Permanent Committee for Research and Fatwa and Shaikh Abd al-Azeez ibn Baz. Decision 7-5 of the Assembly of Muslim Jurists of America suggests making an exception for jobs that do not involve dealing directly with usury, which includes preparing documentation, acting as a witness or providing any help or service, if one needs to take up such a job because one cannot find a legitimate job elsewhere.
