Addressing the Conservative Political Action Congress, he vowed to always put American citizens first and build a "great, great border wall".
He also promised to focus on "getting bad people out of this country".
Mr Trump was greeted by chants of "USA, USA, USA!" as he addressed the annual forum in Maryland.
"We're building the wall," Mr Trump said in his keynote address on Friday.
"In fact it's going to start very soon. Way ahead of schedule. It's way, way, way ahead of schedule."
