Quick rule of thumb on internships. If they ask for or require class credit, they tend to mean it. This means you need to get it through school. If you are a film student, you can ask me. We should be able to apply summer internship work to the fall, so you may not need to pay more for it. If you are a grad and they ask for class credit, you likely aren't eligible for the position. You can, however, take a specific class at some community colleges designed to give credit for an internship. I'd only consider that if you have the money to do it and it's a great position. Some NBC interns have done that. Some people apply and then get the course if they get the position. If there's no mention of class credit, keep in mind that some places are more flexible on requiring interns to be students. Some places are happy to take graduates. They tend to be older, more experienced, and have more available hours. If the ad says "college credit is offered," that can mean they offer it if YOU want it. They may not require you to get it. Which means they may not require you to be a student. The requirement that students get credit is so that companies technically fulfill a legal requirement that the position has an education component. Some worry about that. Some don't. Most bigger places do worry about that, though, and want interns to get credit. Some places pay interns AND require college credit as a precaution. Make sense?
Most of the concern is over this case. As of right now, the interns have lost, but it has changed the business. http://deadline.com/2015/07/black-swan-interns-lawsuit-overturned-1201467302/
