Declan Rice's change of association from the Republic of Ireland to England has been approved by FIFA, the governing body has announced.
The 20-year-old West Ham star informed the FAI of his decision to declare for Gareth Southgate's team last month following months of speculation about his international future.
That move has now been rubber-stamped.
"FIFA can now confirm that the change of association of Declan Rice from Republic of Ireland to England has been approved," said a spokesman for the world governing body.
Rice, who was born in London, qualified for Ireland through his grandparents and played three senior international friendlies for Ireland in 2018 having previously represented Ireland at underage level.
However, he was free to switch allegiance to his country of birth as he did not feature in a competitive game for Ireland.
Rice is now eligible for selection for England as Southgate prepares to announce his squad for the Euro 2020 qualifiers against Czech Republic and Montenegro next week.
