I don't think that's correct.

And while imprisonment may well provide punishment and sequester criminals away from public life for a time, that may be all it does: A large body of research finds that spending time in prison or jail doesn’t lower the risk that someone will offend again. In some instances, it actually raises the likelihood that they will commit future crimes.

It may deter people like you and me, should we consider crime an option for some unforeseen reason. But, for people prone to crime (for whatever reason), it isn't a significant deterrence.

As one of those sources said, the certainty of getting caught is a deterrent. But actual incarceration isn't. We're just keeping them out of society for a time, and actually increasing risk for future crimes.

I think for a serious crime (like murder), OK. Send them to prison, and then deport them (unless the receiving nation agrees to house them in one of their prisons). For simple robbery, or other similar crimes, just get them out. Seems like a waste of resources otherwise.
