This is cruel to international families. My wife and I cannot live in the US (I am a citizen) because Trump banned immigration from her country in his previous ban, so she cannot obtain a residency visa. Luckily her country isn’t cruel towards families and allows me to live here.
The US also doesn’t allow residence for in-laws (only blood relatives of citizens). Meaning we would have to leave my wife’s mother alone for 5 years until she could become a citizen and finish the application - if we were allowed to move to the US.
