University hiring is basically rekt. Throwing out baby with the bath water per usual with this admin...
Most won't be filled at all.
Green cards are almost useless for hiring, as the processing times are too long. "We would like to offer you this position, but conditionally. We still need a year or two to handle the bureaucracy, and we can't say for sure if we are actually allowed to hire you. Please don't accept another position meanwhile."
