If your visa has expired or has been cancelled, and you have remained in the UK without making an application for a new one, the Home Office will consider you in breach of UK immigration laws.

If you are found to be in breach of immigration law or the conditions of your immigration status, you could be detained in an immigration removal centre and, potentially, face deportation from the UK. In extreme cases, you could be banned from re-entering the country for a period of up to 10 years
