Guadalupe García de Rayos was 14-years-old when she moved to the US from Mexico.
After she was caught using a fake Social Security number during a raid in 2008 at a water park where she worked, she had been required to attend an annual meeting with US Immigration and Customs Enforcement (ICE).
After a review of her case and some questions, in previous years she had been allowed to leave.
In 2013 she was allowed to stay in the United States even after a judge issued a deportation order against her because she did not pose a threat to anyone, and did not fit any of Mr Obama’s criteria for priority deportation.
But this year her meeting with ICE ended differently and she was taken into custody and ordered to be deported.
Her detention sparked protests in Arizona, where one man tied himself to the wheels of an immigration van and at least six demonstrators were arrested.
Immigration advocates said they believed her deportation reflects the Trump administration’s hard line on illegal immigration.
“ICE had done what President Trump wanted — which is deport and separate our families,” Carlos Garcia, the director of immigration rights group Puente Arizona, told CNN.
While President Obama’s administration prioritised deporting people who were deemed a threat to public or national safety, had ties to criminal gangs, or had committed serious offences or a number of smaller crimes, Mr Trump’s definition of “criminal alien” is so broad it could be applied to the majority of unauthorised immigrants.
