Getting TN, but flying from Antigua -> San Francisco?

[hohead]

I'll be getting a 3 year TN, but will be vacationing in the carribean first.
So I'll be flying from Antigua to Atlanta (a connecting flight) to San Francisco.

ANU -> ATL -> SFO

The problem is, I don't know where I will talk to the USCIS agents. I'm concerned I will have to do the TN process in Atlanta (my connecting flight), and will risk missing my flight.

Does anyone know where I will go through US Customs & Immigration on this flight?

Thanks!

You will go thru POE in Atlanta and get TN there.

Crap. That means I might miss my connecting flight (depending upon how long USCIS take to give me my TN).

Ohh well, at least I can mentally prepare myself.

Thanks for the quick reply!
