A Stamford mother ordered to return to her home country of Guatemala Monday has had her plea to stay denied, her lawyer says.

Attorney Glenn Formica says Miriam Martinez returned to her Stamford home to take care of her daughter, rather than board a flight to her native country. Formica says ICE agents will have to come and get her if they want her.

Earlier in the day, she went to Immigration and Customs Enforcement headquarters in Hartford to seek to delay the deportation.

According to a spokesman for Formica's office, Martinez came to the United States in 1992 and applied for asylum.

He says her attorney at the time withdrew the application and signed her up for voluntary deportation. Martinez never left but has been checking in with immigration authorities since 2012.

At her last check-in a few weeks ago, she was told to leave, and a request for a stay of deportation in August was denied without explanation.

Martinez and her husband have two daughters who are U.S. citizens. Her 12-year-old, Brianna, has Type 1 diabetes. Martinez is who administers the girl's insulin injections.

"I'm so scared -- I don't want to leave my family," Martinez says.

Martinez is the children's primary caretaker, and she says she fears for her daughter's health if she leaves. Her husband, Raphael Benavides, works in New York and says he cannot always respond to their daughter's health care needs.

"Alone, I cannot do this," he says. "Alone, I will not be able to take care of her."

"Personally, I think its offensive to make ICE officers enforce this," Formica says. "I think it's putting the life of a 12-year-old at risk."

Gov. Dannel Malloy visited New Haven Monday in support of Martinez, and he also blasted Washington's immigration crackdown.

"The American people did not ask for what's happening here to take place," the governor says. "I plead with ICE to allow for sufficient time for other avenues to be explored."
