Should I submit my payment by mail?

[veezbo]

<p>The Facebook page for Common App says that credit card payments can take up to 48 hours to process, and this payment needs to go through before I can submit my application.</p>

<p>My question is, if I submit a check by mail with postmark November 1st, will the system still let me submit the rest of my application? (even though the college will not have received my payment yet)</p>

<p>Thanks for any help.</p>

<p>bump? :(</p>

<p>Update though: I did submit the payment for UChicago, and that seemed to be accepted almost immediately.</p>
