Based on your case, likely you would get a denial. Visacreeen is one of important documents that shows if you qualify or not working as a nurse in USA. Without it any your further application will be the same (get deny). Since a visacreeen takes a quite long term to get it, you may not have time for you this notice you may just receive (based on your English, you sound to need more time). So, better get a working visa instead of applying green card before you get everything ready for it.
