If you are in detention, your application will usually be expedited. This means your case will be given priority and your matter will be listed for a hearing date as soon as possible.
The Judge hearing your case will decide whether you need to attend in person. Sometimes, arrangements are made for you to attend in person; sometimes, if the detention centre can accommodate a video-link, you might attend your hearing remotely.
For more information about attending remotely see Electronic hearings.
