Withdrawal of applications Where an applicant has submitted an application for leave to remain, if they travel outside the Common Travel Area before they have received a decision on the application, their application will be treated as withdrawn (see Immigration Rules, Part 1, para 34K). This is confirmed in the ‘Validation, variation and withdrawal of applications’ guidance, version 4.0, published on 15 October 2021 (Validation, variation and withdrawal of applications): If a person travels outside the common travel area (CTA) before a decision is made on their application for leave to remain, you must treat the application as withdrawn
