Good luck, hopefully its faster than my experience. I've been married to a US Citizen for 9 years and we are currently trying to immigrate from NZ to the US. We are at 390 days since we sent in our initial petition and still have another 30-45 days left.
Others will be able to give you advice on the K1 visa process but don't be surprised if there is a decent wait. Unsure if you will be able to stay in the US once your 8 days are up.
Be patient, read everything 100 times to make sure you understand it correctly and make use of VisaJourney.
An alternative would be to bring your girlfriend/fiance to NZ and then apply for the Visas from here. I have had friends that did that so they could stay together throughout the process.
I’m in NZ at the moment currrntly waiting for my K1 to be approved. It’s a long wait but seems to be speeding up slowly. I’m at 108 days waiting but people are in their 200 days. Average seems to be about 170 day wait at the moment.
