Sometimes deals can be arranged with countries of origin (or nearby), even if it takes time and diplomatic effort (and probably some compensation to the receiver).
If that fails, and anyways until that succeeds (if ever), you still have to treat these people as humans with dignity and rights.
If they are criminals, they serve their time like anyone else.
But first and foremost, if only for pragmatic reasons, society should look for ways to integrate these individuals in a way which benefits everyone; as a productive member. Most people don’t strive to live in misery, and they probably came to your country in hopes of a better future. Help them build that, and everybody might win.
The alternative is to become a monster yourself and still have no answers.
