If you are refused, you will receive a written notice from the Entry Clearance Officer (ECO) detailing the reasons why you have been refused. A full right of appeal against refusal only exists for certain categories and the ECO will inform you at the time of refusal if you have the right to appeal.

For information: Visitors to the UK (business or tourists) and students on courses of less than six months duration do not have a full right of appeal.
