US Citizen and Immigrants Services

So, I came by here the other day for a friend who had an upcoming citizenship interview wanting a copy of the Citizenship book that has all kinds of facts about U.S. history.
I was greeted by the security guard who told me that the office only gives out one book per registered candidate. I politely asked if I could request another one, or if he could ask someone there if there was a copy on-​line I could download.
So he goes in the back and takes a while, then comes back out and says that I could not obtain one for another person in their absence and he wasn’t sure if there were on-​line exams or practice tests — best of luck to me and my friend in other words.
And I thought to myself, if its this difficult getting information as a citizen from people who actually work for the US government and probably will for the rest of their lives, how hard is it for permanent residents going through the process themselves? Especially when I saw a stack of books containing the information I needed just sitting over at this booth just a few feet ahead of us.
If this were a normal business — this obviously wouldn’t work out too well. I found what I needed for my friend on-​line later that night — but that was certainly a waste of my lunch hour for sure.
Must be nice to have a job everyday that is ‘that’ secure. Right.
