With Trump, the Dems, and the GOPe united, amnesty will sail through Congress and Trump will oversee its implementation.
Pure speculation on your part. The border fence has already been budgeted. Current law exists, if inforced, will prevent mass immigration. The H-1B visa and refugee programs are run by the Dept. of State, which is part of the Executive Branch.
Trump, as president, can reverse all of this without the “help” of the GOPe or congress.
