The immigration crackdown in Arizona has apparently led some legal visitors to stay out of the state.
U.S. Customs and Border Protection says total cross-border visits into Arizona in the months after Gov. Jan Brewer signed Senate Bill 1070 fell 17 percent compared with the same period in 2009.
Mexico issued a warning to its citizens about travel in Arizona four days after Brewer signed the measure.
The drop-off amounts to about 12,500 fewer people entering Arizona daily.
Experts say a decline in visitors to the border can’t all be attributed to immigration.
The recession and increased wait times at ports of entry also play a role, although there is no way to calculate which factors are most important.
