That rationale doesn't wash. If someone is here ILLEGALLY, why would they be permitted to step in front of everyone else and serve in the military?
Beats me.

Maybe "stop-loss" had something to do with it.
DACA is simply a
deferral of deportation and a chance to
apply for naturalization, BTW.
Here are the requirements for DACA:
under 31 years of age as of June 15, 2012;
came to the U.S. while under the age of 16;
have continuously resided in the U.S. from June 15, 2007 to the present. (For purposes of calculating this five year period, brief and innocent absences from the United States for humanitarian reasons will not be included);
entered the U.S. without inspection or fell out of lawful visa status before June 15, 2012;
were physically present in the United States on June 15, 2012, and at the time of making the request for consideration of deferred action with USCIS;
are currently in school, have graduated from high school, have obtained a GED, or have been honorably discharged from the Coast Guard or armed forces;
have not been convicted of a felony offense, a significant misdemeanor, or more than three misdemeanors of any kind; and
do not pose a threat to national security or public safety.

So as you can see, and as I keep telling liberals
JOINING THE MILITARY IS NOT EVEN PART OF DACA.
An immigrant would have had to have
already served and be honorably discharged (as well as meet all the other requirements) to be eligible under DACA.
