Worried about the local upshot of the inflow of undocumented immigrants into the country, three Utah sheriffs have made recent forays to the U.S.-Mexico border to get first-hand accounts of what’s happening there.

Weber County Sheriff Ryan Arbon, one of the three, said Utah is feeling the ripple effects of illegal immigration. Part of his aim was to get a clearer understanding of the issues factoring in the surge in the number of undocumented immigrants in the border area.

“What does happen there does impact Utah, does impact our county. We just don’t know the full extent,” he said Wednesday, a day after returning from a visit to the Arizona-Mexico border area. Local residents have been inundating his office with calls expressing concern over border security, he said, and he needs more and better information from federal officials to adjust to the problem.
