The TN program is easier than that. For the EEA you have to go down to the immigration registration office and, well, register.

For the TN program you simply present yourself to the immigration officer when you enter the country (this part is something that even a citizen will have to do), show them your documentation, pay $50, and you're done. You don't even have to fill out a form.

Yeah but in EEA you don't have to explain just how you're a Computer Systems Analyst and not a software developer
