For now they're just waiting, separately, each living with relatives. There is zero guidance. The US consulate did not provide a reason for rejecting it other than the freeze, so there's nothing to even appeal.
Moving his wife and kid to his birth country isn't really an option. He doesn't plan to stay there. He has no job, no house, and no social network there. He barely speaks the language. His wife (US born) has a job and family here, and his kid only speaks English. Asking them to pull their kid out of school and move to another country until the US consulate decides to start processing paperwork again doesn't really seem like a reasonable solution, though with every passing week and month, it may end up being the only way they can be together again.
