Yes they could and on the old board I proposed a plan.
DACA becomes a legal plan passed by congress with these paramaters:
It applies ONLY to those currently in the DACA program. It is plainly stated that if you were brought into the country after the creation of DACA by Obama, you are NOT eligible PERIOD, and expect to be deported (you can thank mummy and daddy for going back to a country you know little to nothing about).
There is a hard date that DACA ends. Permits will be renewed a total of 5 times (10 years). You break the law (felony or more than 2 misdemeanors) and you will be deported. Those in the program can start the application process to become a citizen. If you have not become a citizen in 10 years time, you will NOT be allowed to work under DACA and are once again subject to immediate deportation.
There is NO chain migration under DACA. Parents here illegally – they are still subject to immediate arrest and deportation. No family member or relative gets guaranteed immigration.
