Thank you both for the input. I was unaware that Panama are closing the Friendly Nations Visa window. I'm not sure that I'm ready to commit to living in Panama just yet.
My general plan was to base the corporation there and continue being a true Nomad for a few more years (perhaps forever, or until health declines; I'm nearly 40). Before covid I was travelling 365 day a year for several years (visiting the US periodically to keep the green card). Now that Covid is subsiding, I'm back to travelling (been in Europe since May with a rental car until November and I've been︀ visiting various countries). Even during Covid I was renting long-term airbnb's. I haven't rented aa︁ real apartment since 2017. Committing to living in one place will be a big step︂ for me.
My understanding is that Panama allows foreigners to own corporations in Panama, meaning︃ my plan should be possible,. But, if I'm wrong about that, then I should jump︄ on the Friendly Nations visa.
I've been to Panama many times and have spent extended︅ periods there. I greatly prefer being outside the major cities (Panama city is too noisy︆ for me)... and fortunately I'm very strong in Spanish so I can communicate just about︇ everywhere.
