There is something wrong with this. Not knowing all the details and just going off of your post, I will note the following.
Since this pension is based off of a financial need, the applicant's financial statement needs to be included otherwise how would the VA know they meet that requirement???
Is your dad regularly seen at the VA? Do they have a copy of his DD214 (discharge papers)?
It doesn't sound as though you got a copy of the application, which is a big mistake.
Did you sign and include form 21-22a making you your dad's "Claimant's Representative, or did the social worker assign the VA?
Based on your posting, it sounds as though there were many mis-steps. I have never heard of it being this easy to submit an application, and from what you are saying it looks like a lot of supporting documentation was not included with the application.
Did you research the application process on this? There is a posting on this forum that gives an excellent outline of what needs to be done.
http://veteranaid.org/forums/index.php/topic,264.0.htmlAt this point you don't want to do anything until you hear back from them on the application. To do anything now would only complicate things and you don't want to do that. When you get your letter if proper documentation was not included, you will need to address it then.
