A power outage at the offices where US immigration officials were last night processing the deportation of Aisling Brady McCarthy has disrupted her return home to Ireland.
The nanny was arrested yesterday afternoon for violation of her visa.
Ms Brady McCarthy moved to Boston in 2002 but had been living there illegally for over a decade after her holiday visa expired.
She presented herself to federal agents from the US department of immigration and customs enforcement (ICE) yesterday afternoon.
The Cavan woman had bought a plane ticket home through her lawyer, Melinda Thompson, and had been hoping to fly home as soon as possible.
However, the process was disrupted by a power outage at the ICE field office in Boston.
Officials were working to process her file in order for her to make her flight, however it remained unclear if it would be cleared in time for her to make the flight.
If she does not return home overnight, it is expected she will likely fly home later today.
ICE spokesman Shawn Neudauer said: "Brady-McCarthy entered the United States in 2002 on a tourist visa from Ireland and never left. As a significant visa violator she is an ICE enforcement priority.
"She was issued a final order of removal from the United States in 2013 and will remain in ICE custody pending deportation from the US."
Ms Thompson said the Cavan woman was "ready to go home" and was hopeful the deportation process could be sped up following her ordeal.
Ms Thompson said her client had not received any apology from the US authorities and that "the criminal justice system here failed her".
She said her colleagues may now examine if she could sue the US for her treatment after the District Attorney accepted there was no burden of proof to sustain the homicide charges.
"I think some other lawyers at my firm might be better able to answer (if there is any legal recourse).
"In a perfect world there should be. I don't know what that is, I don't know how you give somebody two-and-a-half years of their life back but I hope there is some way to help and quite frankly make sure this doesn't happen to somebody else," Ms Thompson said.
