Hello,

I don't think you're barred from applying, but it will be a challenge for you to answer why you need a part-time MBA (vs. a full-time degree), beyond the fact that you don't want to wait until next fall's deadlines. If you're unemployed now, consider what other things you could do now to make your application to the full-time program even stronger in the fall, such as devoting yourself to non-profit work. Of course, only do that if it's something that you're truly passionate about, but that would be one example of making good use of your downtime to make a positive impact AND potentially make a stronger case for yourself when you apply.

Good luck!
Scott
