You can apply online now, or fill out a Dependents Application for VA Education Benefits VA Form 22-5490 and send it to the VA regional benefit office where you want to go to school.
But what if I've already started my educational program? Can I still get the benefits?
Of course, just ask a certifying official from your school or your employer to fill out a VA Enrollment Certification VA Form 22-1999. They'll need to submit it online using VA Online Certification VA-ONCE.
