No, not the immigration of zombies – I mean programs, in this case "temporary" amnesties, that never die.
Today was the last day for illegal aliens and legal visitors from Liberia to register for Temporary Protected Status. Congress created TPS in 1990 to allow the executive to suspend deportations of (and grant work permits to) illegal aliens from countries where there's been a natural disaster or civil strife. I've written frequently about the bogus nature of TPS (here and here, for instance), but always regarding the fact that while the status isn't technically permanent, like a green card, it's nonetheless renewed indefinitely, long after the home-country emergency has passed. An earlier crop of Liberian illegals, for instance, was granted a "temporary" amnesty in 1991 – and they're still here.
