There's not that many legal hoops at all. WIth a bachelor's degree it's pretty simple to get an H-1B visa. I'm from Canada and a ton of my friends get jobs at tech companies after graduation with no problem. Larger companies like Google, Facebook, Microsoft, Zynga are obviously more open to this type of thing, but many of my friends have gotten jobs at early-stage startups as well. You can also start your own tech startup via this "loophole".

You may also want to look at the expected value of being one of the early engineers at a tech startup. My prior is that it is significantly lower than the expected value of starting one.
