You are wrong. Lots of people are wrong on that topic. An alien here in America has a right to trial by jury and for a felony, etc., he has a right to be indicted by a Grand Jury. Yet an alien here is not a citizen.
Surely SOME of you must, by now, start to glean that at least SOME of the rights accorded to the People under our Constitution apply to PEOPLE not just to CITIZENS.
So your formulation starts off on the wrong track. You can call it bologna or Oscar Mayer, but that just makes you all the more wrong.
NOW then, once we understand that SOME rights belong to JUST citizens (e.g., voting) but SOME rights belong to "persons" (i.e., not just to citizens), then the next thing some of YOU must start to come to grips with is that NOT ALL PHRASES used within the Constitution apply to all people at all times.
For example, by its very terms, the FIFTH Amendment applies to considerations of due process within the context of criminal law, for the most part. You can try to deny that obvious fact, but you cannot succeed since -- when you deny it -- you start off with a false premise.
I'm sorry you have YET to learn the truth of this matter. But the Constitution in MANY regards applies to all people who happen to be here (our right to a jury trial doesn't extend to citizens, either, outside of OUR sovereign reach). And it applies only to the extent it was intended to apply. So, for example, if you are charged with a crime here, regardless of whether you are a citizen or an alien, you ARE equally ENTITLED to a fair trial, a jury, in some cases to a Grand Jury, to a lawyer, and if you can't afford one, to have one appointed to you. The procedural rules are also CONSTITUTIONALLY guaranteed to be the same for you as for anybody else in a similar bind, regardless of your citizenship status.
But it ONLY applies where it was intended to apply. So if you are an enemy of our Republic in time of War, you have no right to "due process."
The Constitution was not drafted by simpletons. They (unlike you in this regard) knew what they were doing. And the claim that the Constitutional right to due process applies to enemy combatants over in Yemen confuses a Constitutional right applicable to a criminal proceeding with some unimaginable "right" of overarching planetary scope in non criminal matters.
You are not merely wrong; you couldn't be more wrong.
