ATLANTA, Georgia (CNN) -- College senior Kyla Berry was looking forward to voting in her first presidential election, even carrying her voter registration card in her wallet.
But about two weeks ago, Berry got disturbing news from local election officials.
"This office has received notification from the state of Georgia indicating that you are not a citizen of the United States and therefore, not eligible to vote," a letter from the Fulton County Department of Registration and Elections said.
But Berry is a U.S. citizen, born in Boston, Massachusetts. She has a passport and a birth certificate to prove it.
The letter, which was dated October 2, gave her a week from the time it was dated to prove her citizenship. There was a problem, though -- the letter was postmarked October 9.
"It was the most bizarre thing. I immediately called my mother and asked her to send me my birth certificate, and then I was like, 'It's too late, apparently,' " Berry said.
Berry is one of more than 50,000 registered Georgia voters who have been "flagged" because of a computer mismatch in their personal identification information. At least 4,500 of those people are having their citizenship questioned and the burden is on them to prove eligibility to vote.
