http://www.visajourney.com/timeline/profile.php?id=26130First thing you should do is start a timeline, and then use the timelines to help you answer questions just like this one.
One other thing, If you have not filed for Visa yet, consider carefully the CR-1 visa (Filing I-130 ONLY) this is an IMMIGRANT visa which costs less than K-3, allows work upon entry to the USA. K-3 requires EAD (90 days to get) to work, and AOS ($1010) to get green-card.
Compare CR-1 and K-3 timelines for your country, for most CR-1 takes slightly longer than K-3 to get.
