So here's my point of view as a conservative person, but not a trump supporter.
The main focus now needs to be on reforming our immigration system so that it is easier for hardworking people to come to the US. While illegal immigrants may currently be an important part of our labor force, at the end of the day they came here illegally and should be subject to punishment as such. The only way to end illegal immigration is to fix the system and create a more feasible process for legal immigration.
