International
Meara, who qualified for Irish citizenship through his grandparents, was named to the Republic of Ireland U-21 team on April 30, 2012.[19] However, the Red Bulls did not permit him to train with Ireland, despite the fact that the call-up would not require him to miss any MLS games.[20]
