The US Senate has confirmed the nomination of Claire Cronin as the next US Ambassador to Ireland.
It was the final step in the appointment process and Ms Cronin is expected to take up the role in the near future.
Her nomination was approved by the US Senate Foreign Relations Committee in October.
She appeared before a virtual confirmation hearing in September and addressed issues including corporation tax and the Northern Ireland Protocol.
Ms Cronin said that if she was confirmed as ambassador, she would work closely with the US Congress and the Biden administration to advance US priorities and reinforce shared values in Ireland.
"When my grandfather left Donegal for the promise that America held, I can't help but wonder what he would have thought if he knew his granddaughter would one day be testifying before this esteemed committee as the nominee to be the US Ambassador to Ireland," she said at the time.
Ms Cronin currently serves as a Representative and as a Majority Leader in the state legislature of Massachusetts.
She is also a lawyer and campaigned for Joe Biden in Massachusetts ahead of the 2020 presidential election.
She was nominated for the role of ambassador by Mr Biden in June.
