The Herbasite website is interesting but regarding many of the places outside Vietnam which were sprayed with dioxins - the govt has been vague.
The VA while its personnel are professional and nice -- fights every claim where the disease is not on the presumptive list. And the VA is very inconsistent. So much so -- some people want to form a class action suit.
Each state has State paid VA assistance program separate from the federal program.
There are 33 legitimate Military Organizations like Military Offficers Association of American, Disabled American Veterans, VFW, American Legion etc. Some of these 33 groups have volunteer assistance programs
quality varies.
Good luck
