States of Malaysia
Sabah and Sarawak have additional powers as part of the terms when they joined Malaysia, such as immigration controls. They have separate immigration policies and controls and a unique residency status. Passports are required even for Malaysians for travelling between these two states or between either state and Peninsular Malaysia, however Peninsular Malaysians who are on social/business visits up to three months are allowed to produce a MyKad or birth certificate and fill in a special form in lieu of a passport.
