It is the policy of the United States not to deport apprehended aliens back to Cuba. If not the alien, then, I say send Castro the hospital bill:

When he [an illegal alien from Cuba] suffered a stroke following a recent arrest, his medical bills hit $400,000. Now, he’s paralyzed and in a wheelchair. He needs to be in a nursing home. So what’s next for the suspected criminal that’s in the country illegally? It’s tough to say. But one thing’s for sure. Douglas County cannot afford to spend any more money on the man, whose last arrest was for cocaine trafficking. The sheriff’s office had to ask the county commission recently for more money to cover the man’s medical bill.
