BUFFALO, N.Y. -- The undocumented workers who were employed at four Western New York Mexican restaurants raided last week were having their cases heard by a deportation officer Tuesday.

Members of the clergy and PUSH Buffalo are helping the workers and their families, after many were displaced due to the raids.

Immigration attorney Matthew Kolken said the federal government exercises great discretion in determining who should be deported.

In 2014, President Obama explained how Immigrations and Customs Enforcement would prioritize which undocumented immigrants would be deported.

"Felons, not families," the President said. "Criminals, not children. Gang members, not a mom who's working hard to provide for her kids. We'll prioritize, just like law enforcement does every day."

Kolken said the government also takes into consideration the hardship that a deportation could cause -- like deporting a parent who has a citizen child.

"I feel as though if in fact there is an opportunity for these people to stay in the United States, we will all work in concert to make sure that that happens," Kolken said.
