If your spouse is in the U.S. and is eligible to adjust status, then just file the Adjustment package with the I-130 receipt. It will be processed as an immediate relative case.
If your spouse is outside the U.S., then you should have received a responseon the I-130 within about 6 months of notifying the CIS that you acquired citizenship status. You will need to notify them again.
Please contact me if you wish to engage experienced counsel on this matter.
