For 10 years, Samuel Demetrio has worked in the fields near Linden.

Originally from Mexico and not a legal citizen, he's worried immigration agents could show up at any time.

"Yes, because I could lose my job," said Demetrio, speaking in Spanish in a grape vineyard where he manages workers as a foreman.

According to the California Farm Bureau Federation, they are not aware of farms being audited by ICE or enforcement activities taking place.

However, they are aware of enforcement taking place in area warehouses.

"We would advise them to comply with all state, local and federal laws," says California Farm Bureau Federation Communications/News Division Manager Dave Kranz when it comes to growers.

"Should we be the police force? I don't believe that we should be," says Linden grower Frank Stonebarger.

Stonebarger, who has grown cherries and walnuts for over three decades, says he has no choice but to comply.

"If the federal government comes on this property, I don't think anybody is going to be happy about having the federal government come into their business and look you down one side and down the other. But, in the 35 years I have been doing it, I have always tried to comply with the regulations," says Stonebarger.

Bruce Blodgett with San Joaquin Farm Bureau Federation puts the blame for the conflict between state and federal law on state lawmakers.

"It's one of those situations where our state legislature over stepped their bounds. When you look at what they're asking employers to do is break federal law. It's really a no-win situation for the grower," said Blodgett.

For workers like Samuel Demetrio, who says he has a wife who is not legal, but two children who are, he just wants to work in peace without fear of deportation.

"We need paperwork so we can be legal," said Demetrio.
