Coyotes... She can't fly to her home country due to asylum but can go elsewhere... I'm not sure how many people she has funded to come over. Drives very nice cars and yet does 4-5 buildings herself, and it has been family covering her slack when she goes south most of the time.
From other sources, I hear that it's 50% upfront for the cartel. Her flying down and funding family isn't that risky, as they live with her or nearby and she most likely pays them.
I occasionally work in other buildings with the same cleaning company and also with others. All seem to be doing it that way.
So they work for cash with a green card holder bringing them in the country. Then work to pay off their trafficking in fees. I'm sure this is quite common and in all types of work.
Note: She doesn't own the cleaning company...
