There is a difference though in the benefits between SSI and SSDI, 2 very different benefits. For neither one would monies have to be repaid, but there is a difference between them in what happens when someone returns to work and the amount of money one earns before losing the benefit.

Vocational Rehab indicated school is not necessarily indicative of the ability to work. If after you get your degree, if not able to, things should remain the same. If can work part-time, verify what would happen as it could affect current SSI benefits from that point forward either lessening them or losing them all together depending on the amount of your income. Just check with the office that does your reviews, at what point would income affect your benefit.
