I wonder how this would work with a K-1 "Fiancé" Visa. Typically a K-1 holder can enter the country as long as they get married within 90 days, and then the family stays together while the I-485 is processed. Now what? Come to the USA, marry the US Citizen, and then you're banished back to your home country?
There's also the K-3 which lets the foreign spouse enter as a non-immigrant to keep the family together while the I-485 is processed. Are they getting rid of that entirely?
This is all totally bonkers, likely not well thought out, and pretty cruel to families, which is completely on-point for this Administration.
