You should get it Oct 1st. Understand that your scholarship is FY 2011. FY run Oct 1 to Sept 30, thus you fall into 11.
Additionally, even AD, pay is not forward, but back. In other words, you have to work 30 days before you get your monthly stipend. Just because you are there Aug 30th, it doesn't mean you will get a stipend Sept 1st. You need to complete the entire month.
If I recall correctly the other thing to understand about stipends is if it falls on a weekend, the money will not be in your account until Monday. In other words, the 1st hits on a Saturday, don't assume the money will be there at close of business Friday because it won't. It will be there first thing Monday a.m.
Ag and I x posted. I am coming from an AF POV and did the worst thing..ASSUMED that all branches are the same. We all know what Assume means.
It is also important to understand, that sometime kinks in the system exist and it can take months to work it out...Sorry, but I can tell you from personal experience that is true...one wrong digit inputted in the direct deposit number and your money is floating around in the black hole of cyber space.
