When that knock comes at the door of an undocumented person, it's too late to start making a plan. 

"You will leave here basically with only what's on your back," Susan Cruz explains to families fearing deportation. 

Cruz was born in El Salvador and founded Sin Fronteras, a non-profit that helps young immigrants in conflict with the law. US immigration agents in Texas, Georgia and South Carolina this week launched a campaign to detain and deport a number of undocumented immigrants.. 

About 120 individuals have been deported so far — many of them women and children.

Cruz encourages the undocumented to take three simple steps — and to take them now. 

"If and when somebody shows up to the home to notify children that their parent has been detained by immigration or that something has happened to their parent, the child can just pull this envelope out and hand it over to the police or to the social worker that arrives to the home," Cruz says.
