That's very wide. Say, if i need more changes to my information. I should get into contact with veterans affairs?
Absolutely. An up to date information is always preferred because it could affect your rating or payment. Changes could include marital status, birth of a baby, child adoption or any other life changes.
I heard form some people that disability compensations could be increased. How's that?
That information is correct. IF you have a disability rating which goes over 30%, you can get a higher payment adding eligible dependents.
