quick question regarding TN application

I have all of the required documents and I will be driving down to Buffalo Peace Bridge for the TN application, later on that day I plan to apply for the US Social Security Number at the close by office.

Since this is my first time crossing boarders and I just started to drive recently, I am not familiar with the processes and etc.

So my question is:
1. Where exactly do I apply for the TN visa, do I do it at the time when I cross the boarder booth or is there an office after I cross the bridge?

2. I know the application fee for the TN visa is $50 + 7 for the I94 card, I think. Do I need to pay other fees upon crossing?

Thank you for those who can help me on those questions.

you cross the border as if you were entering the States, you tell the agent you'd like to make a "Request for TN Status", they'll tell you to park and go into the office. Its around $60 I believe, bring US cash.

thank you very much for your help

And yes, you'll need toll money for the bridge. It looks like it's 3.00 and if you're coming back into Canada, you'll need to pay again. Good luck!

didn't notice that toll fee on their website
