Peru timelines and immigration

His interview went well, mostly they just asked questions about his previous marriage. He was married when he was 18 and they divorced a few years later. None of the questions were about the validity of our marriage, we've been together for 8 years so it's pretty obvious that we are a real couple. Since then, it hasn't budged. I've contacted the embassy not too long ago and they tell me that the file is still "under evaluation" and to wait until they contact us. It will be 3 months since the interview in about a week. So we are now at 15 months processing, the medicals have expired (confirmed on GMCS notes). So i ended up ordering the GMCS notes in early December and i just received it a week ago, from what i see the interview did in fact go very well and they were happy with his answers. The GMCS notes show that the Eligibility is "in process" and that the criminal and security are still at "not started". It seems like we might have to wait a while longer. It's very difficult because we can't afford for me to fly out and see him that often, i just can't wait for it to be all over.
