Not necessarily, it seems.

If it takes an infinite amount of time for a chunk of matter to reach the event horizon of a black hole, and the black hole will evaporte completely in less time then that, wouldn't that mean that any matter falling towards a black hole won't acutally reach the event horizon? The black hole should evaporate completely before you ever get there!
It doesn't take an infinite amount of time for the chunk of matter, only for an outside observer!

'What about Hawking radiation? Won't the black hole evaporate before you get there?'

Take a look at our Black Hole FAQ thread.
