The Department of Homeland Security reportedly informed Scott this weekend that Florida would have access to the agency's Systematic Alien Verification for Entitlements database.
The database, known as SAVE, is a list of resident non-citizens maintained by the agency and would help the state to challenge people's right to vote if they are suspected of not being U.S. citizens.
The Obama administration had for months denied Florida's request but relented after a judge ruled in the state's favor in a related voter-purge matter.
"Access to the SAVE database will ensure that non-citizens do not vote in future Florida elections," the governor said. "I'm appreciative that the federal government is working with us cooperatively… This commitment from the United States Department of Homeland Security marks a significant victory for Florida and for the integrity of our election system."
