For permanent, it takes about eight months. On the temporary side, just over the last few months we finalized the service standards. For a VIP or urgent request, it's 48 hours; for China, it's five days; for what we call tier 1 countries, which includes Saudi Arabia, India, Haiti, Pakistan—there's another one missing—it's 10 days; and for the other countries, for tier 2, it's 20 days.
