First, here is the LAW:
Suspension of entry or imposition of restrictions by President:
Whenever the President finds that the entry of any aliens or of any class of aliens into the United States would be detrimental to the interests of the United States, he may by proclamation, and for such period as he shall deem necessary, suspend the entry of all aliens or any class of aliens as immigrants or nonimmigrants, or impose on the entry of aliens any restrictions he may deem to be appropriate.
This would seem to be authority for this, as well:
HOWEVER…those granted visas and green cards were given due process in order to come here. It SEEMS to me that they are being deprived of due process in the EA. BUT- the law certainly seems to give the authority to PREVENT those holding visas and green cards from coming back.
If you are IN THE USA, it a different ballgame.
The Constitution mentions the word CITIZEN only in making qualifications for office, and in differentiating between various states of the nation. Once you are here you are a PERSON as defined by the founding doc.
That means your rights are no different than ours and, is precisely why Guantanamo is in Cuba.
Perhaps it can be argued that by not passing thru customs these persons are NOT in the USA. I don’t know the fine points of that.
But I do know that DEPORTATION should require due process and the PERSONS if here, cannot be deprived of this any more than any of us can be.
I hope this judge’s ruling is rushed to SCOTUS. The people should be HELD until then so that the pressure remains on our system to resolve this at ‘Trump’ speed.
BTW, every nation but one on that list either has an active Islamic revolt, or land being held by Islamist killers. The other nation is IRAN.
