Mario Hernandez has lived in the United States for almost 50 years.
He has raised his children here, served during the Vietnam War, and worked as a federal employee in a federal prison.
But Hernandez just found out that he is not a U.S. citizen - and his fate living in the U.S. is now unknown.
Hernandez left Cuba when he was nine years old, but his parents never filled out the required paperwork for him to become a citizen.
"I feel like I've been punched in the stomach, but I've also felt like the carpet's been pulled from underneath my feet," he said.
Hernandez is due back for another immigration interview on Wednesday.

UPDATE: According to Jeopardy's Facebook page, Julia Collins had her 12th victory on the show this week and continues to compete for more.
How do you become Jeopardy’s first female 10-time champion?
For Julia Collins, the strategy is simple: "Be the first one to ring in and answer the question correctly ... I try to just keep control of the game board."
But it takes more than buzzer speed to keep winning match after match.
On "New Day" Monday, this former art history major credited her love of reading – everything from US Weekly to CNN – and a well-trained memory, for her success.
"I think I'm lucky to have a good memory, and I think I've trained that part of my brain to work as well as possible," she said.
Collins, who has her masters in supply chain management but is currently between jobs, has won $220,610 on the show.
She is the longest-running female champion in the show’s history, and is a couple of thousand dollars away from cracking its list of top five money winners.
If she succeeds, she'll become the highest grossing female contestant in Jeopardy history.

At $2,520,700 in winnings, Ken Jennings is the highest grossing Jeopardy contestant of all time.
He's also the record holder for concurrent wins with an unprecedented 74-game streak in 2004.
While Collins said her playing has shown "I fall in the ranks of people who are really great at this no matter what their gender," she's proud to set a new bar for women.
"I'm a big proponent of women being the best that they can be," she said. "It's exciting to have my own little, tiny, tiny place in that."
