Illegal aliens are already disqualified from citizenship, residency, working, voting etc...just for being illegal aliens and not American citizens...
Immigrants cannot vote or get a government job...post office, fed, state or local ...only American citizens can work for the gov...or vote...
However immigrants can enlist in the military...but they still cannot vote...nor work for the government when they separate from the military...
You need a reality check.
Immigrants vote in large numbers.
