Make sure you find out about the Bechtel International Center (generally called the I-Center). Their phone number is 723-1831. They're the place to go for information on Visas, and they have sessions on how to fill in tax forms, get driving licenses etc. These sessions are generally mind-bogglingly boring and frustrating (much better to just ask a friend who (really) knows), but sometimes there's just no better way to get the necessary information. When you register with the I-Center, you also get on their mailing list, which keeps you informed of all the activities the I-Center organizes.
