Both the United States and Ireland allow for dual citizenship. A benefit of dual Irish-American citizenship is the right to live and work throughout the European Union, the United States and all her outlying territories. There are four ways to obtain dual Irish-American citizenship -- birth in Ireland to an American parent, birth in the U.S. to an Irish parent, an American naturalizing in Ireland and an Irish citizen naturalizing in the U.S. Each avenue to dual Irish-American citizenship requires action through different processes.
Birth in Ireland to an American Parent
Take up physical residence in Ireland. Be present there for three of the four years preceding the birth of the dual Irish-American citizen.
Obtain the Irish birth certificate of the child. The American parent must be a United States citizen at the time of the birth and must have had a physical residence inside the United States for five years. Two of those five years must have taken place after the parents 14th birthday.
Visit the U.S. State Department's website and search the database for the nearest U.S. embassy or consulate. Gather proof of the American citizenship of the parent and proof the parent fulfilled the residency requirement. Documents may include a passport and U.S. tax forms.
Register the birth abroad with the U.S. embassy or consulate. The embassy or consulate will register the birth certificate which then can be used to prove both American and Irish citizenship for the child.
