The government has had more than enough time to fix this issue. DACA is the temporary fix which been in place for almost for six years. Extension of DACA is only going to cause more issues and backlog with immigration. I think they should let us know what they're plans are so they can we can move forward be it a permanent fix or no fix at all. Saying that they would revisit this issue in 2020 or 2021 is highly unlikely. Having a two temporary status also has it cons , you will eventually run into issues with getting certain jobs especially good paying jobs and important things like buying a house.
