Start the process now and get it over with. It took me over 2 weeks to get verified with mtgox and dwolla. Mtgox would have just taken a week, but i only sent a utility bill. The verification page says that's all you need, mentions nothing about ID, but they also require a photo ID. Then after 2 weeks when i tried to make a transfer from dwolla to mtgox, i found out dwolla needed an ID. But now I'm glad i went through the hassle and got it done.
Ditto, more or less. Start the process now, and get it over with.
