The "Star Trek" actress shared several photos from her husband Marco Saldana's day becoming a U.S. citizen.
"On our way to be sworn in as a US Citizen. Marco has been dreaming about this moment for a long time," she wrote. "It was a process- as it should be, but we are finally here. We are aware it isn't as easy for many immigrants to obtain their citizenship, we say to them NEVER GIVE UP."
She continued, "Stay the course, America would not be what it is if not for the immigrants that come for better opportunities. We send love and good vibes to you all today."
Saldana, who married Marco in 2013, added her own story about her mother becoming a citizen.
"Her mother arrived in NYC in 1961 and brought my mother from Dominican Republic when she was 10. My sisters and I are indebted to them both. Because of them we are American women. So proud she is here supporting Marco!" she added, along with a sweet picture of her husband and her mother.
She also said that another actor just happened to be there too getting his citizenship.
"Oh check out who is getting their naturalization today too... David Oyelowo and his Wife!!!!! Congrats!" she wrote.
Marco's big day was a family affair as the couple brought their twin sons, Bowie and Cy.
