JEDDAH: The Health Affairs in Jeddah is investigating the circumstances leading to three of its expatriate workers' residency documents being renewed for seven years after it had sacked them. The expatriates are currently in the country and their residency documents are legal. The contracts of the two Arab nurses and one administrative assistant ended in 2004 and they were replaced with Saudi employees. Regulations stipulate that after the end of their contract their residency documents should have been taken by the relevant health affairs authority and their passports handed over to Passports Department prior to their flights home. The department discovered the irregularity when one of the nurses' relatives came to the department a few weeks ago requesting to transfer his relative's sponsorship from the Ministry of Health to him.
