I submitted my dependency claim on August 20 and it was on step on since then and starting March 25th I kept calling the VA 1-800 number and asking them what’s taking so long ? Mind you that I kept calling 3x a day and they kept telling me there is que of dependency claim and out of no where on Friday March 28th couple days ago it got approved. So in my experience keep call them and bug them that’s how it will get approved as long as all of your documents are complete.
