Stina Constantine, who has lived in Australia for the best part of 20 years, faces deportation after an administrative error saw her denied a visa.

Labor Duty Senator for the Riverina Deborah O'Neill has now written to Immigration Minister Alex Hawke to urge him to intervene in Ms Constantine's case.

Ms Constantine, whose immigration case is scheduled to be heard in Federal Court next month, said she did not know about the letter before it was sent or who asked Senator O'Neill to write it.

"This really pleasantly surprises me as I have not been approached, so I can only imagine that someone in the community or a group of people have tried things off their own bat and that to me means so much," Ms Constantine said.

"It speaks volumes about what the Wagga community is like and it's exactly the reason why I don't want to leave this community.

"They have never been anything short of supportive of every endeavour I have tried, so why would you want to go anywhere else when you have got people like that around you?"

Senator O'Neill stated in her letter to Mr Hawke that Wagga residents wanted him to give Ms Constantine "back her life in the community that supports her".

"I have been approached by local Wagga representatives and other upstanding citizens who are devastated at the prospect of Ms Constantine being forced to leave the country she has called home for the last 20 years," Senator O'Neill wrote.

"I am advised that she finds herself in this situation as a consequence of incorrect administrative data initially provided from her educational institution to your department. This was later corrected by the institution.

"An administrative error should not rob this young woman of her future in this country, one which she currently dedicates to helping families of children who are battling life-threatening diseases, running a ministry, and fighting domestic violence in regional NSW."

More than 13,900 people have signed an online petition supporting Ms Constantine to stay in Australia.

Ms Constantine said she had not heard anything more from Mr Hawke's office since her court date was delayed earlier this month.

"When it was delayed, because it was so sudden, I did crash but since then I have sought some help and found some different strategies to be more prepared," she said.

"I'm just trying to do things day by day, like everyone else facing their own battles, and trying not to lose hope."
