You may be referring to a annulment due to "Lack of Form". The Church DOES recognize all marriages, until discerned otherwise. You should not wait, lest the two weeks turn into a longer period and cause you to mess up your wedding day plans.
Who exactly gave you that direction?
My suggestion is to get the impediment removed at your earliest convenience not in a last minute scramble. Also, the more time passes by, the harder it could become to provide pertinent information.
I'm still waiting on my annulment and only turned in my paperwork a month ago,so I have much interest in how this all works, but little to offer in the way of help for what you are going through. My prayers are with you as you go through the process.
