Do you mean anyone can send documents before payment? For your kind information, I am not mis lead anyone. Moreover, he can double sure with the IQAS after the payment. Thank you!
Yes, why not - since they anyway don't open your docs the moment it goes because there is a huge waiting list. So For example even if your document has received earlier and your payment is not done document will not go anywhere because anyway, IQAS runs 2 months behind almost, so think like this and your document certainly has your file number as well. Even on their website is mentioned until your document is not reached they will not move at all, so similarly for payment.
