Residence cards are also issued to resident expatriates working in the Sultanate, and their dependants. The labour card and the residence card have now been combined into one card. Customs Port Sultan Qaboos, Muscat International Airport and all overland crossing points now use an improved Customs computer system. This has been put in place to improve customs clearance procedures and customs clearance offices. These moves are designed to support the national economy and come in response to the Gulf Co-operation Council Customs Union and the Greater Arab Free Trade Zone.

A declaration on a container security and goods inspection initiative has also been signed between the Directorate-General of Customs and its American counterpart, allowing for the inspection of goods transported by sea between Omani and American ports.

The Omani government and the ROP have continuously made road safety their top priority. They have also worked effectively to promote road safety internationally. Oman submitted a draft resolution to the UN General Assembly entitled Road safety must not
