@Bestpal....yes you get a confirmation on the email that you provide them. but i also printed out the completed form just as an "insurance". So when i got there...i just showed the staff the paper...and they told me to get in line where you get ur passport stamped. I guess if you want you take extra copies of PP pics.....just to be on the safe side.
