They can be detained indefinitely, there are many of articles discussing it.

Lets be serious, keeping adults and kids on jail is one thing, keeping adult parents and their children together is another. It actually makes sense , deporting them together if they entered illegally and I would imagine it would be so much cheaper.

Still, the way the process was implemented is perverse. They can keep track of people's property, but not of parents and children. ... hard to believe that this has not been done this way on purpose.
