One that I've just finished re-reading is Green Card by Wendy Richards. Superman has just told Lois Lane that he's from another planet. Unfortunately for Clark, there is a government agency which is quite interested in that information... the INS!

I really enjoyed her take on the whole 'illegal alien' thing in this story. I do generally enjoy her stories, but this is one of my favourites.
