Don’t hold your breath waiting for a weasley Congress to do that - the better situation is the current one: that there is no citizenship to remove; ergo no vote is needed.
Now we just need somebody to start acting as if that’s the case... no D/L’s for illegals, no tuition breaks, no schools, no state/federal benefits, no SS#, and no jobs.
Good luck arguing for that and saying the papers they have possessed for 5 years or even 50 years were never good to begin with.
You will send the GOP to a political grave if you and others argue in favor of that.
