received the same message from the 2nd page but I did not forward to them the language test and police cert because i forwarded it to them before this message - in my understanding, it is just a reminder that if you need to submit it, you need to give them the original copy.
i paid my RPRF and attached thru my gckey account the receipt of payment.
if your concern is your UCI number, it is on top of this message. if you need to submit police clearance and language test, in my understanding you have to submit the original scanned copy to your gckey account. not really an expert so better to ask others with the same case as yours. good luck =)
