FIFA have approved Michael Duffy's transfer of eligibility from Northern Ireland to the Republic of Ireland.
The Dundalk player was previously capped at U-18 level for the Republic and subsequently by Northern Ireland up to U-21 level. A call-up to the North senior squad followed ahead of a World Cup qualifier against the Czech Republic in 2016, but the winger withdrew in advance of the game.
Duffy then caught the attention of Martin O'Neill, who was keen to get him back to the Republic fold in 2018. It didn't happen.
Current manager Stephen Kenny was hoping to have the 26-year-old involved for the start of his tenure but "an issue with his paperwork at FIFA" was, according to Kenny, the reason why Duffy did not get the call-up then.
As well as winning league titles with Dundalk, Duffy also had spells in Scotland with Celtic, Alloa and Dundee.
The Republic of Ireland begin their 2022 World Cup qualifying campaign away to Serbia on 24 March.
