From what I was told, they stopped doing the COR/LOR letter of res. in Trat IO for driving licenses then they got so many complaints, they started doing them again. Somebody somewhere in immigration seems to have come up with this idea on how to pee us off even more, IMO they don't like the extra (FREE for us) work, and i think maybe has to be signed off at least by the office Chief who is often not there, maybe at meetings coming up with more stupidity out on jolly home visits, We all know its corruption when charged for these, you won't get a receipt init. So even if there was a standard legal fee the IO wouldn't be able to pocket it. I M O.
