Having a piece of paper from any school holds no weight, and realistically from what I hear FullSail has a fairly awful reputation.
To be fair though, film school is what you make of it. There are industry professionals who never went to film school, and I'm sure there are people who never even made it close to the industry who studied film at USC.
Film school is great for some people, but more for the skills learned and contacts made during. No-one cares about your piece of paper.
