Empress:
Yes, you can use a birth certificate, but you should also have some form of government issued
picture ID, probably a driver's licence. You don't have to have a passport, but you do have to prove to the INS inspector's satisfaction that you are allowed to enter the US. Driving across the border is a good example where you are usually just verbally asked your citizenship. You might also want to photocopy page 2 (the picture/data page) of your passport. It will have the passport number, as well as demonstrate the approaching expiry date.
Rudi:
If you use your credit card, they'll probably just let your money in.
