When the UK government began to restrict which institutions could offer accredited accounting courses as part of an immigration crackdown in 2011, Iqbar Bahar, a Bangladeshi national, found himself urgently looking for a new college.
In order to gain admission to his chosen institution, Bahar, now 44, took the Test of English for International Communication, a standardised English test facilitated by US company Educational Testing Service.
Years later, on October 30 2014, Bahar received a life-changing letter from the Home Office. The government department accused him of cheating on the test and revoked his visa.
