And how do I apply for this benefits?
To apply to this you need to be about to leave active service soon if you have been discharged within the past year or if you are dependent of a veteran.
I see, that's very interesting. The only way  to apply to this is by the web?
No, not really. You can also use the mail  for your application. You need an educational/vocational counseling application VA form 28-8832, which you have to download.
