YES! It actually is!
The O-1 is literally the visa of artisan craftsman of choice. So a "master mason" can literally put together a portfolio of published works and gain entrance based on that traditional craft knowledge.
But like, it will be scrutinized intensely for the actual artistic value. And then any renewal will be like: "so what have you done lately?" ... the mason would have to open a company, have trained a team, and be producing off the chain shit like in Tehran if they want to renew.
I've hired more than one O-1 architect through the years.
