See: Hollywood star Arnold Schwarzenegger's 40-year journey as an American

Actor-turned politician Arnold Schwarzenegger announced on Instagram on Monday morning that he had completed 40 years as an American citizen. He said: “To think that a once scrawny boy from Austria could grow up to become governor of the state of California, that is an immigrant’s dream. In school when the teacher would talk about America, I would daydream about coming here.” Schwarzenegger shared several of his milestone pictures. Here are our picks.

Here's looking at the 'scrawny' boy from Austria.

"As long as I live, I will never forget the day when I raised my right hand and I took the oath of citizenship. You know how proud I was? I was so proud that I walked around with the American flag around my shoulders all day long,” he said.

“I finally arrived here in 1968. What a special day it was. I remembered I arrived here with empty pockets but full of dreams, full of determination and full of desire,” the 'Total Recall' star said. “Everything about America seemed so big to me, so open, so possible,' he continued.

A weighlifter and a fitness enthusiast, he became Mr Universe at the age of 20.

“To my fellow immigrants listening tonight, I want you to know how welcomed you are. We encourage your dreams. We believe in your future,” said the actor-turned-politician who went on to become the Governor of California.

The action star recently opened up about the complications he experienced after undergoing his third open-heart surgery. But he also spoke of how he managed to bounce back through sheer hard work and determination.
