In trying to follow my DS but yet stand off in the background I find myself confused. LOA - I know what it stands for but I'm still a little short of the full understanding. My DS was told by his B&G (good guy) that if the admission board sends him a LOA the Senators and Congressman will be well aware of the letter and will have a copy for their own file. Can someone please tell me the full depth of what the LOA truly means? Sounds like the LOA's are far and few to be given out. I don't think my DS would get an LOA but it would be good to understand fully in the event he does. Thank you in advance.
