If you have no other viable option or if you would rather just be deported, you or an attorney can apply for you to leave voluntarily at your own expense. The judge will only grant this if you can show that you have enough money to buy your own passage if you have a valid travel document and if you can convince the judge that you will not stay beyond the set date of departure. Talk to an attorney to find out more about asking for voluntary departure – it is much nicer than actually being deported.
