Including spouse in GC application

I am planning to apply for NIW and would like to include my spouse in my application. How will I be able to do that, and at what stage? Please advise!

to Lance:

You can include your spouse in your I-140 form by listing your spouse as a dependent, then you can file I-485 together and get your green cards.

Hi everyone! I have a question about citations count. Is it like the most important factor for USCIS now? I heard from an attorney that in recent years USCIS paid extra attention to citation numbers from the RFE cases.

I don't have many citations but I have technologies that were commercialized. There are products that follow the commercialization as well as great revenues generated. Would this be sufficient to compensate for the low citation count?

to Lance:

Basically what @Emma said. But your spouse do not to file I-485 together with you. She can file whenever suits her. She'll need your Approval Notice though.
