Sorry for the VERY late reply, my summer got crazy with work and life and then I jetted off to the UK for a visit.
Thank you both for the help. My sponsor is my Dad, who has a full retirement from teaching public schools and is still working as an adjunct professor at the same college where I am working. My parents both have great retirement plans from their jobs and they are willing to support us until Alan is settled in and working. I have been picking up more hours at the community college where I teach so do have a better salary than over the past few years, but I am not yet considered full time and still come up short on income. Alan is a math and science teacher in a secondary school, so employability should not be an issue for him. There's been a horrible teacher shortage lately, especially in STEM. We've already had his transcripts reviewed and have full information for what he needs to begin the process of getting a teaching license in MA. He can even start the process while he's in the UK so that will help him speed things up. I made sure to double check with the state regarding what he needs to do when I called to ask about the possibility of me moving from university level teaching to taking a position in a local high school.
We have been doing regular visits throughout this time, and have plenty of documentation from friends, family, etc that we regularly interact. He and the kids have been to the USA 2-5 times a year and I try to get to the UK at least once a year. We're on a video call almost 24/7, chat on whatsapp daily and pretty much anyone who knows either of us is well aware of our unusual situation. I have no problem showing chat records, phone logs, photos, statements, etc. and we can show that we have regularly seen each other until covid kind of put a halt to everything after summer of 2020. I'm actually over in the UK now, typing this as he's working on his timetable for the fall semester of teaching. It's been nice to just sit here and do work like a normal couple, which I'm sure most people would think sounds odd....but the VJ community would understand
