The actual permit is two of those home-printed business cards, printed side by side and folded together at the perforation. Before laminating, it is 3.5" wide by 2" high; the crude laminate job makes it too wide for most wallets.
The day mine arrived, I tried to trim the original laminate... and it came apart, helpfully dumping the cards out without damaging them.
I carefully trimmed about 1/8" off mine with a paper slicer. The D.I.Y. laminating pouches I bought at Staples added that back to it after more careful trimming, and it fits into my wallet OK now.
