The 38-year-old "Guardians of the Galaxy" star expressed her happiness by sharing on Instagram a picture of Italian-born artist driving to receive his US citizenship.
"On our way to be sworn in as a US Citizen. Marco has been dreaming about this moment for a long time. It was a process- as it should be, but we are finally here," Saldana said.
Calling it a task the actress said, "We are aware it isn't as easy for many immigrants to obtain their citizenship, we say to them NEVER GIVE UP."
