If you don't have a computer engineering degree I'd forget about trying to obtain a TN. I'm Canadian and was working in the US for many years as a web developer under the TN "scientific technologist" category. I don't have a CE degree, and it was generally very iffy whether they'd extend the TN each year, but they did... until 2008 when they started coming down really hard. I don't know if they started cracking down on TN's in general, but long story short... even while working legally in the United States and holding a valid TN I ended up getting flagged in the US customs database as an illegal immigrant and will probably have trouble if I even try to visit the country again.
