There are many VA Programs and Services.
Title 38 of the United States Code. Visit the VA Web Page at:
There are General Eligibility Requirements. Certain benefits require wartime service, and there are Documents required to expedite evaluation of services.
I went through a year long process of getting my 89 year old Dad qualified for VA Aid and Attendance Benefits, 4 years USN WWII Pacific:
He was "qualified" in that he was not able to tend to his own needs and I was granted Legal Custodian Status and Federal Fiduciary Status to handle his VA Benefits.
There were Documents in his case where as his Representative I had to legally agree that he was relinquishing rights to posses or have access to firearms.
