However, the law makes it illegal for sponsors and employers to retain employees’ passports and travel documents once their residence permits have been issued.
According to Article 4, any expatriate once dismissed from his job or quit on his own will not be allowed to re-enter the country before the elapse of two years from the date of his departure.
However, this condition can be waived by the Minister of Interior, or whoever represents him. Also the department (to be designated later) in charge of enforcing the law may exempt some cases from this period based on a written permission from the expatriates’ previous sponsor, according to Article 4.
The new law gives the Minister or whoever represents him the power to transfer sponsorship temporarily if there is a legal dispute between the sponsor and the expatriate worker.
