I am driving up to Canada tonight crossing at the I-81 border. In the past I have been able to go into Canada and get back to the US with just a drivers license. I know I do not need a passport but when checking the entry requirements it states proof of US Citizenship required. Does a drivers license still cover this requirement? I am a US State Department employee and a qualification for employment is US Citizenship, do you think my US State Department ID would work? Thanks!!

PS. I have a Passport but I forgot it this morning (D'oh!) and I do not have time to get it unless I break dinner plans with my cousin who I have not seen in over 2 years who is flying back to KL tonight.

PPS. I will be traveling with your typical American family (Mom, Dad, & 5 year old daughter) who will have their passports if that makes any difference (Suspicion wise)

There's the "rules" and then there's what you might get away with. Officially you need proof of citizenship & photo ID. However, I crossed from Canada into the US (and then home again) last week with a birth certificate and driver's license and they never even opened the birth cert - So your mileage may vary.

Best you can do is wing it and see what happens.

I winged it and had no problems. Coming back to the US I was asked for my birth certificate (which I didn't have) but my State Dept ID worked just fine. The agent already knew employment meant I was a citizen ^
