Resident visas to expatriate workers are allowed in respect of identified professions where there is a dearth of qualified personnel. Existing visa regulations do not permit migrant workers either to change their professions or the institutions in which they have been authorised to work, which is the basis on which the visa is issued.
Article 54:

Protection against dismissal, quantum of remuneration, period of employment, etc., are governed by the terms of individual contracts entered into between the worker and the organisation which employs him. A visa issued to an expatriate worker under the visa regulations is limited to a pre-identified job assignment."
