I'm a victim of radiation. I was born in a different country but am a permanent resident here (green card holder). I have all paperwork and proof. I had pneumonia 3 times as a child and bronchitis. I have really bad lungs and I'm very limited to what I can do. I moved out of state so I don't have a doctor here . Do I need diagnosis from a doctor in order to receive social security disability? Or can I use my victim of radiation card as proof? Please help.
