You have the option of voluntarily leaving the country if you have not been detained. DHS offers non-legal immigrants the opportunity to do so before a particular date. You have to go to an Official of the country at an Embassy or Consulate that is not within the US to sign form G-146 or I-210 ("Verification of Exit").

You must take any of the 2 forms provided by DHS to the Embassy or Consulate; related documents such as the surety agreement and other additional documents; Official identification with photo, and proof of the date of departure from the country, such as boarding passes, if you crossed by car, gas receipts or bus ticket, etc.

Also, you can investigate if you are a candidate for an adjustment of immigration status to obtain your Green Card.  It is possible to obtain it through a residence request made by a relative or through an asylum request.

Similarly, if you believe that your human rights were violated throughout this process, you can file a complaint with DHS.

ICE has a tool for locating people who have been detained. Enter if you think any of your family members have been detained: https://locator.ice.gov/odls/
