Immigration reform requires that Congress act. It requires legislation from Congress, and the Republicans are blocking any and all attempts at immigration reform.
President Obama has tried to provide some interim relief in the form of DACA, expanded DACA, and DAPA. However, even there, the Republicans, lead by Texas have blocked the implementation of expanded DACA and DAPA. The Supreme Court evenly divided on the appeal of the injection issued to prevent expanded DACA and DAPA from going into eﬀect, meaning that the injunction remains in place, and there will be no expanded DACA or DAPA.
2016 being an election year, Congress will not do anything for at least the rest of the year.
The only possibility for comprehensive immigration reform lies in Clinton becoming President and the Democrats taking control of at least the US Senate. That means that the earliest that immigration reform could become a reality is mid-2017, and there are many hurdles to overcome in getting there.
