G-325 that I did (Rev.09/11/00) had 4 copies. I didn't even notice till yesterday they have two G-325 & G-325 A. So when I filled out the form using USCIS website I just filled up the first page than rest 3 more pages were copied automatically. All I did is print them & mail them with my medical report as instructed by USCIS March,2005.
I have noticed very carefully both G-325 & G-325 A but they are exactly the same. I don't think it should be a problem if one does G-325 instead of G-325 A. Well, after sending mine I was not asked to send another one.
By the way like I mentioned earlier I didn't even notice than that there are two kinds of G-325. Therefore I just downloaded G-325 form from USCIS website & yesterday when I was checking the copy that I sent (Xerox copy that I saved) all the way bottom of that form it says FORM G-325A although it was downloaded under G-325 not G-325A.
You know USCIS process all theses things that is sometimes or you could say most of the times very confusing. All their instructions carry so many meanings that it's hard to figure it out who did it right & who's wrong.
Atleast in my case that's what I sent but I was not asked to send them another one. So I guess they accepted it well. As a matter of fact USCIS even mentioned that in my LUD message that they received my medical & G-325A (Biographic Info) as they requested.
