Get Help with Voluntary Return
Those who make their own plans to return to their own country may also get extra help. You should contact the voluntary returns service to check what help you can get. They will also inform you how long it may take for them to arrange your return home.

Note: You can get help applying for travel documents and assistance to book your flight. But, they can force you to return to your own country. It can happen if you withdraw your application or fail to follow the application process.
Final Part in the Voluntary Returns Service
Once the Home Office receives your application they will contact you within 14 days. In some cases they may ask you to provide further information to support it. They can cancel your application if you fail to provide any requested information.
After the Home Office approves your application you must leave the UK within 3 months of that date.
Note: There are further steps to take for those who apply for asylum in the United Kingdom. In this case you must cancel your application. You will need to sign a 'declaration of withdrawal' at the time of leaving the UK.
