It all depends on when your actual EAS dates shows on the DD214.
For example: Say your EAS is 2/28, You take terminal (start date 2/1) even though they give you your DD214 while on Terminal you can upload it. VA doesn't take it until 1 Day after EAS date Due to not be classified as a veteran until the day after. They take about 30-40 days to re open claims, check correct address, look over DD214 and make sure your banking info is correct. Once that's done you should see it open and will start to get benefits.
Now how they pay works: Your EAS +1 Day so in this example 3/1 would be the start date- 4/1 comes You wont see money because its always for the month before -2/1-2/28, 5/1 Comes it will be for 3/1-3/31.
Once you call they will tell you this exact breakdown.
