1. A real fence.
2. Get rid of the anchor baby laws.
3. Fine those who hire illegals.
4. Allow any LEO to arrest illegals.
5. See Sheriff Joe about housing illegals unitl they are deported.
Congress could take care of 2, 3, and 4 in one day, if they wanted to. Look what they did to kill the terminal (port) deal.
#2 is going to require a constitutional amendment due to the unfortunate wording of the 14th Amendment.
As for #3: that will NEVER get done, because that means fining Mr. and Mrs. John Doe, those fine upstanding citizens who are against sin and in favor of motherhood. (News flash: a majority of prostitutes are mothers.) People oppose illegal immigration--and they oppose measures against illegal immigration that might inconvenience or punish them.
Your #2 would require ammending the constitution, which for one I agree with, but it may take more than a few days.
Love the idea of Sherrif Joe being in charge of detention!!!
