This is insane, I replied this once already and nothing here to show for it, lol...
Okay, have your attorney send you a copy of your filed petition. I have a feeling he/she didn't submit everything.
I had this happen to me so it can and does happen. If you have never received a copy of the petition, you NEED to have it, actually 2 copies, one for you and one for your fiance. Be sure they send you two copies.

It is best not to be so quick to judge without knowing all the facts and stick to the questions asked by the OP.

You have a big uphill battle ahead of you, but you also have the gift of time and VJ in your arsenal! I highly suggest you use both to the fullest! As recommended, she needs to come for another visit and you need to get lots of pictures! Friends, family, different places, days and times. Not staged photos where you are always posing for the camera either! Real life experiences captured. It helps to designate a friend for this purpose.
Age will be addressed, be prepared with what you will say when asked. If you get an interview, you need to be fully prepared. Yet even that doesnt guarantee you a visa. So this is a love story, but your love alone will not see you through from a CO's point of view. Your character will be judged, your every movement will be watched. This is no picnic in the park. You must literally prove this isn't fraudulent, and if you go in there stating what you have stated in your post as to why there are no pics over the course of that many years, and no additional evidence, you will be denied.
You have come here to VJ, we all read what you say and we are strangers just as is the CO. Have you convinced any of us that this is real? I can only speak for myself, tho reading the responses given I can bet how many of us think there may be something going on that isn't on the up and up. And that is my final piece of advice. Think about what you are divulging and in what context, because if you can tell virtual strangers this information and we think something is up, imagine what the CO is gonna think! We can only go off of what you tell us, and I am not judging, just saying how it appears to the naked eye.
I dont want you to feel like we are ganging up on you, because truthfully, the best advice you can get is on this site. The harsh reality of it can hurt but if you use it and turn it around to be proactive in your case then you will be better off.

It's clear now that your file has been approved by USCIS again to proceed with another interview.

It's been a while since I last posted on here, but this topic (and the replies that followed) is one close to my heart and I thought I would share my experiences in the hope it will help the OP (or anyone else for that matter). I totally agree and relate to all the replies said before - that things WILL get better. My situation mirrors your husband's in so many ways. I moved to the US (I'm the UKC) to be with my US wife and 2 month old son (I was waiting for the K1 visa while he was born) about 2 and a half years ago. We stayed with her father for the first month, which was difficult in so many ways. I thought once we got our own place everything would fall into place and I would feel happier. Actually the opposite happened and I got incredibly homesick to the point I was arguing with my wife over stupid things. At one point I even announced I was ready to move back to the UK just because I was so unhappy with the situation - new country, being a dad for the first time, no job, etc. I am so glad I stuck it out though!
Fast forward to today. I have a job that pays half what I earned in UK, I still get frustrated with the American way of doing things and I do miss a lot of the creature comforts from the old country (foods, TV programmes, friends and family). But my advice (which has already been said a number of times by previous posters) is - it DOES get better - a LOT. Once you get your own place, he gets a job, starts to make friends, and ultimately starts to live his life again - it will all start to settle down. There will be numerous times he will get frustrated with the American way, he will get homesick many times and he will just feel like a fish outta water! These are things he will have to get over and I don't think they will ever go away. Keep talking as a couple and listen to what bothers him the most. Then ask yourself what you can do to make it right? As an example if it is New Zealand foods he misses - then find either an international store close by or improvise with an American equivalent. Misses the rugby? Then subscribe to a cable TV channel that shows rugby.
In the end always remind him (and yourself) of the main reason he is here - to be with you because you love each other. Everything else is small compared to that. I wish you both the best and always know you have friends on VJ who have been here before!
