I got a New Zealand green card, my girlfriend is in China, and I plan to get married. How can I get her a green card?

It is suggested to get married in New Zealand, which saves the translation of marriage certificate. Then you need a lot of things to prove your relationship. For example, the proof of living together for several years means that the letters to both of you are sent to one address, and the photos are needless to say, but it is best to have a certificate from someone who knows you better (in New Zealand), and it is best to have a receipt for your gift to each other, as well as a joint bank account and so on. So the proof must be several years, not just one or two months now, because there are too many fake marriages. Generally speaking, it won't take long, but the immigration officer will definitely ask you to make up this card and that card, which will delay the time. You may ask for an interview, but not necessarily. But you don't have to wait until you immigrate to New Zealand. You can stay for a long time as long as you get a tourist visa and postpone it.
