I interpreted that to mean they may not have permanent US immigration issues vs "being deported".
1. getting those with criminal records depoarted and not allowed back (a fair number of whom have been depoted and have violated the ban on returning)
2. getting those who've wished to settle and work jobs to leave voluntarily by buying them plane tickets and giving them cash stipends and not barring their reentry in the future
These Koreans who came to Georgia on behalf of their company will probably not have their tickets paid for by the US nor get the stipend, so yes, they are treated differently as you suggest.
after the surprise arrests executing the judicial warrant, the Korean company and government stepped forward and expressed a commitment to helping these workers, which occurred without negotiation, although you could call the flurry of phone calls after that negotiations, it was probably more like "Q; what do we need to do" "A: you need to bring them home". neither country nor the companies involved is looking to disturb relations, though perhaps this is adjacent to a tariff negotiation.
