Pillar to Post Franchise

Hi all, I’m currently in the USA on an E3 visa and looking to switch to an E2 visa, and the best way to do this is buying a franchise, I’m looking at Pillar to Post, just wondering if anyone has any feedback, yes I know a lot of people are anti franchise, but this makes sense for me in my situation, any idea about failure rates anything I should know? Thanks in advance.
