You will need your Social Security number, VA file number, the new school you plan to attend, and some other information.
Are you the dependent of a Veteran or service member?
no I'm a veteran
I have all that info you said I needed so how do I change my school?
You will need to submit a Request for Change of Program or Place of Training, VA Form 22-1995. The form can be completed online.  I can give you a link to VA Form 22-1995
can I do it by mail?
Yes, just download VA Form 22-1995, fill it out, and send it in to the VA regional claims processing office that is in the same region as your school. I can give you a list of regional processing offices if you need it.
can someone help me so I don't make any mistakes?
If you need help you can work with a trained professional called an accredited representative to get help requesting a change to your benefits.  I can provide you with more information on  how to get help submitting your request
if I do it myself I just send it in to you guys?
