Question, I have filed 4 SBRs over the last several weeks.  All E filed form 1s.  I just got a rejection email for the first one, submitted on 6/'9/16.  It is because the serial number is wrong, i forgot the letters that are in front of the numbers (stupid on my part).  I know of course to resubmit it but if i check the other 3 and they are incorrect can i fix them or do i have to wait for them to be rejected first?  

Of course if i have to wait for them to be rejected and they take too long i wont be able to get them resubmitted in time before the 13th is why i ask.

thanks

You could resubmit the corrected form, then email the ATF with the rejected form number and the corrected one for the first one and wait for a approval or do all four at once and see if you get a batch approval.
