I agree you can put D/S. I might also ask if you are a U.S. CItizen? If so you can file form I-130 and I-485 a the same time along with the other required documents. Marriage based adjustment of status cases take around 6 months and your wife can also apply for a work permit at the same time get it after 3 months. Don't forget to include significant evidence that the marriage is bonafide. If you are a greencard holder you will have to wait for your priority date is current before you can file the I-485.
If you would like to have an immigration attorney prepare and file your case you may call me for a free consultation. As a solo attorney I am able to charge less than the larger immigration firms who must pay staff. (206) 724-1940.
