hey granted im not an expert like Peter is, But I have gone through a similar series of events as you are describing here. I transferred to the US on a L1B visa in 2022 and after an unfortunate round of layoffs late 2023 I scrambled for another role and managed to get sponsored and obtain O1 status. I had a good background of experience working on some prestigious products, a degree and written testimonials from people "high" up in my industry, studio heads, people high up in award academies etc. there may be extra steps for you as you don't have a degree (if I'm reading that right) but i believe you can prove you have had "equivalent training" to a degree maybe using your experience.
