An individual who has been deported from the UK must apply in writing for revocation of the deportation order and wait for the outcome of the revocation before they can travel to the UK or before they can apply for entry clearance. An application for entry clearance for a person who has not had a deportation order revoked, will be refused automatically. An application for the revocation of a deportation order can be made at any time, but in a case of a conviction for an offence for which the person was sentenced to a period of imprisonment of less than 4 years, 10 years should have elapsed since the making of the deportation order.
