Yup, resubmit. It'll still take 4-5 weeks though based on my experience.
you'll need to re-apply...i just got mine back it took 5 days... don't forget to check if you need get a new border ATT. In Ontario our border ATT's are tied in with our Form 6.
Here's a link to a fillable Form 6NIA pdf. http://www.atf.gov/forms/pdfs/f53303d.pdf just type out your info and print then fax to (304) 616-4551
hope this helps
I called them and advised them that I just needed to add ammo on my list as I got my form 6 approved but forgot to add what kind and quantity of ammo.
I was advised to resubmit.
Have added another 'toy' to my list and resubmitted again.
I have 3 form 6's sitting around from last year !
Doesnt make sense but that's the only way.
Make sure you bring the invitation to shoot in the US with you when you cross into the US.
PS my ATT does cover transport up to a Canadian/US border.
Good Luck.
