Arnold Schwarzenegger’s weighing in on the current firestorm over immigration — saying America’s always been about opening its arms … but he says newcomers need to play by the rules and act right when they show up.

The 77-year-old hit “The View” Tuesday, reflecting on arriving in the U.S. from Austria at 21 with nothing — no ties, no help — yet still built a dream life. He says others can do the same … if they arrive legally and act like respectful guests in the U.S.

Arnold kept driving the point home — saying everything he’s achieved, from pumping iron to box office hits to running California, he owes to America.
