A lot of farmers use farm hands from Mexico with permits and a form of green card that allows them to get paid in American dollars during work seasons to bring back home, and get a path towards American citizenship than if they just entered the country with a passport or applied directly for a visa.
I don’t know if a lot of contractors do the same thing, but I wouldn’t be shocked. The labor is cheap and it kinda looks good for the camera. Adam Raguesa, a YouTube chef, has a good video on how farmers in the modern era grow the crops we eat on the table every day.
According to one of the mods, the admins required it. According to the admins and bot creator, they didn’t put that into place. https://lemmy.dbzer0.com/post/29791336
