In the event that your visa application is refused, you will be informed in writing of the refusal and the reason(s) for the decision. You have 2 months from the date of the refusal letter to submit an appeal in writing with any supporting documentation. The appeal should fully address all of the reasons for which your application was refused.
Appeals should be submitted to:
The Appeals Officer
Visa Office
Embassy of Ireland
Montpellier House
106 Brompton Road
Knightsbridge
London SW3 1JJ
You will be informed in writing of the outcome of your appeal. You may only appeal the original decision once. You may, however, lodge a new visa application at a later stage.
