If i am entering the US from canada by land, do i need a passport?

Question

would birth certificates and drivers licenses suffice?

Answer 1

Your birth certificate and drivers license will work, until Jan. '09. Over the weekend I crossed with my ID and birth certificate with no problems.

Answer 2

At this point they would still let you in, but in believe that is changing in 09.

Answer 3

birth certificate and drivers licence is all you need. you hit the nail ont he head.  The passport law doesn't come into effect until June 2009 (if it doesn't get pushed back again).

Yes proof of citeznship will work just fine.
