All American figure skaters (not just Jason) are effectively self-sponsoring athletes. USFS gives some funding to skaters depending on their results in the previous season. Jason is currently in Team A, tier 2, receiving the second-highest possible level of support:

As far as I know, the USFS doesn't announce the amounts of money given to the athletes in each tier. But there seems to be universal agreement that it isn't nearly enough to cover the cost of training. This is why American skaters seek sponsorships, do shows and competitions with large prizes such as Japan Open...and come from families with enough wealth to cover their children's training costs or the willingness to make extraordinary financial sacrifices to support their children's dreams.
