You should make sure that your selected program is approved for VA training. If you are not clear on this point, VA will inform you and the school or company about the requirements.
Obtain and complete VA Form 22-1990, Application for Education Benefits. Send it to the VA regional office with jurisdiction over the State where you will train. If you are not on active duty, send copy 4 (Member Copy) of your DD Form 214, Certificate of Release or Discharge From Active Duty. If you are on active duty, you must have your enrollment approved by your base Education Services Officer, and you must have your service verified by your Commanding Officer.
If you have started training, take your application and Member Copy of DD Form 214 to your school or employer. Ask them to complete VA Form 22-1999, Enrollment Certification, and send all the forms to VA.
If you wish to withdraw your contributions from VEAP, obtain and complete VA Form 22-5281, Application for Refund of Educational Contributions, and send it to your nearest VA regional office.
