The fear is that more and more migrant laborers who could work here legally will elect to stay home instead of risking arrest or harassment by coming to the U.S., adding to an already worsening labor shortage.

The concern, Williams says, stems in part from what farmers are already experiencing – a nervous and anxious workforce.

"On the first day of the Trump administration, we got calls from farmers saying, 'My workers are afraid to leave the farm,' " he said. "People are scared to show their face."

To understand the level of worry, you have to understand how much the agriculture industry here and across the country depends on foreign labor.

Bittner will tell you quite bluntly that the work they do is work most local people don't want to do. It's outdoors. It's hard physical labor. And it tends to be seasonal.

Right now, he has 20 workers; but come harvest time, he'll add another 25 in order to get his apples off the trees in time. He says the workers tend to be people from rural areas or people with a farm background.

"I have workers who are worried," he said. "There's also a lot of anxiety among the farmers out there. No one seems to know what's going to happen with the current administration."
