A lot of guys from my Det had EAD's right after their graduation but when it came time to cut orders, they kept getting pushed back further and furter and endied up with an EAD about 3-4 weeks before their IFS date. I was lucky and my EAD was 3 weeks before my IFS date from the start so I figured it was probably correct. From what I've seen here at Columbus, unless you are an academy guy or OTS guy being on casual for a long time is rare.
