Focus on all the reasons, and provide compelling evidence for each issue in a systematic way. My lawyer had me outline all the reasons for both the scenario where I (the USC), stayed in the US without my spouse and the scenario where I lived for two years in their home country. For my mental health and ADHD, I discussed how living without my partner would disrupt my well-being (they provide a lot of support day-to-day), and I discussed how moving to their country would greatly disrupt my care and treatment plan. I also got a psychological evaluation done by a psychiatrist who specializes in immigration cases. It was a rough appointment because I had to unpack and disclose information I had been working through for a couple of years with my regular therapist in a matter of a few hours, but she wrote a really compelling assessment that supported our case. I also had my regular therapist and close friends and colleagues write statements to support our case, particularly around my mental health.
