I agree. Lets get our definitions right.

DACA was "Nonimmigrant" but now is/will be "Illegal Alien" as soon as their temporary status is not renewed. (Refer to #4 - 'Illegal alien:  an alien who entered the United States legally but who has fallen "out of status" and is deportable.')


Correct terminology, continuing on:

#1-Immigrant-An alien who has been granted the right by the USCIS to reside permanently in the United States
#2-Nonimmigrant-An alien who has been granted the right by the USCIS to reside temporarily in the United States. 
#3-Alien-An individual who is not a U.S. citizen or U.S. national.
#4-Illegal Alien- Also known as an "Undocumented Alien," is an alien who has entered the United States illegally and is deportable if apprehended, or an alien who entered the United States legally but who has fallen "out of status" and is deportable.
