Practicing anesthesia without US residency?

I always thought you cant practice without doing residency here , but i recently found out at my friend's institution has MDs from other countries, practicing anesthesia at the institution without doing a residency in the US. the MD is from abroad, mostly asia. Some of them did a 1 yr fellowship here and others didnt. Obviously not board certified. anyone know more about this in terms of legally and billing? are the institutions just billing for them as a department? how are they getting... Practicing anesthesia without US residency?
