Their parents apply and they are granted aid. Like I've stated many many times in this thread... if you don't like the law... work to change it.
Are we going to qualify that only US citizens who are parented by US citizens can get welfare?
I don't think ANYBODY should get welfare. My parents were migrant (U.S. citizen migrant like the Okies) farmworkers after their parents lost their farms in the Depression. They managed to get themselves out of the fields, put themselves through trade school and us through college without ANY welfare or free healthcare....not even free school lunches.
