Application Fee Payment: Your application fee will be available for payment within three business days of submitting your application. Your application is considered "on time" if submitted by the deadline, regardless if the fee is paid on that date. However, your application will not be evaluated if you do not pay the fee once it is due. To pay the fee log onto your GIAC MyStatus and pay the application fee.

i saw somebody mentioning how fee payment link would prompt just after submitting but nothing sort of this happened with me and neither does the above message justify it, any thoughts?
