What happens to my visa if I lost my passport?
What happens to my visa if I lost my passport? Once the loss or theft of a passport is reported, the visa is revoked for security purposes. Therefore, even if the documents are found or returned later, the visa will no longer be valid for travel.
Does the UK embassy keep your passport?
Your passport will be returned to you by the Embassy approved courier service. To ensure that there are no delays with the delivery, you must register with courier at the time you schedule the appointment for the visa interview.
