*** Moving from K3- an obsolete visa- to CR-1 spousal visa ****
Your process will be the same as anyone else up until interview, see Guide here: http://www.visajourney.com/content/i130guide1. He will be denied at interview due to the deportation. Then you will need to file a waiver. How difficult that will be depends on why he was deported (overstay, crimes, etc), and what kind of bars he has (for example, with an overstay, there is a 3 year bar for 180-365 days, or a ten year bar for 1 year+ overstay). The fact that he was deported, as opposed to leaving by himself/ getting voluntary departure will make things more difficult. Check out our waivers forum here: http://www.visajourney.com/forums/forum/113-waivers-i-601-and-i-212-and-administrative-processes-221g/ and you may want to post the details of why he was deported and timeline of events there for best advice.
