You likely won't run into trouble - but why run the risk? Have the adult U.S. citizen be fully responsible for the bond. Also, keep in mind that you may be eligible for deferred action for childhood arrivals (DACA), which would save you from deportation if you are approved. You should consult an immigration attorney who could advise you of your rights.

I suggest you consult with an experienced immigration attorney to determine what needs to be done.
