Your question is a bit incomplete. Do you require a waiver because you are not lawfully present in the United States? Would your departure cause extreme hardship to your wife? These are a couple of the issues that would clarify your eligibility for the provisional waiver (which requires a filing of form 601a). Also, I am not sure what your concern is. If you are eligible for a provisional waiver, the procedure is for you to email the NVC and notify them that you will be filing a 601a and that they should not immediately schedule you for an appointment at the U.S. Embassy in your country of origin. I would strongly suggest that you contact qualified immigration counsel.

If you are planning to consular process to return to the U.S. and if you have accrued over 180 days unlawful presence, then you will need the waiver.
The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
It would appear from the letter you require a waiver. You should be concerned, as these waivers are complex and difficult to obtain. If you aren't already you NEED to work with an experienced immigration attorney. My firm handles such claims throughout the US.
