How are you going to remove the parents of DACA (who broke the law bringing them here), their aunts, uncles, cousins, siblings, etc. after you give DACA amnesty?
DACA was never legal, they are still illegal aliens fluent in Spanish, still citizens of their own countries.
Any amnesty will be exploited if you look at all the previous amnesties.
DAPA which attempted to follow DACA was stopped by federal court injunction brought originally by a couple of Freepers one of whom is me. Governor Abbott tasked the Texas AG to sue Obama and his DAPA in federal court. DAPA was eventually dropped by DOJ under the Trump Administration.
The answer to your question regarding illegal parents is found in the Trump Administration policy as to the CLEANUP. It’s all right there.
