    Most people who are subject to immigration control and are not detained are on temporary admission, which usually includes regular reporting requirements. They will have been given a form called IS96.
    Asylum seekers who apply at a port of entry may be granted temporary admission to the UK and given an IS96 letter, which can later be used to obtain an ARC. IS96 letters may also be issued to people who are released from detention.
