At six-seven months before,
just get a new one, when you are not in a hurry.
Many stories of people getting bitten by this.
Why push it to squeeze out another $5-10 of time value.
I always request 48-pager,
usually by stapling a big hand-written full page note to the application!
Even then, it came back short one time.
I took it back down to the Post Office,
a corrected one was sent to my address within 10 days or so.
