Storm chasing is mostly an independent hobby. There isn't a formal association to join nor are there any official rules or guidelines to follow.
If you're new to the hobby and have little or no experience observing severe storms, I highly suggest that you avoid chasing alone. Instead, seek out an experienced chaser or chase tour group in your area to help you learn the ropes. You'll have a much better (not to mention safer) time if you go about it that way.
There is one group that organized somewhat of a chasers "club" back in 1977, and it still contains some of the most reputable chasers in the U.S. to this date. They used to publish a magazine called "Storm Track" which is now fully online. The forum on their site contains lots of valuable knowledge and tips from the pros.

Storm chaser is not an occupation, it's a hobby. The only people who get paid to do it are just a few people who are doing research on severe weather.

You can, but it is difficult. For the vast majority of storm chasers it is a hobby. Only a few storm chasers are actually professional chasers.

You don't need to take college to become a storm chaser. I do suggest attending a storm spotter class to better understand storms and tornadoes.
