Federal agents are reminding the public that anyone entering the U.S. from another country must report cash exceeding $10,000.
It's not illegal to enter the U.S. with more than $10,000, but there can be trouble if it's not disclosed. The rule extends to checks or other monetary instruments.
The government says it has seized more than $5 million since October at Michigan border entries, up 24 percent compared to the same period a year ago. Two Canadians accused of smuggling cash earlier this month had $59,000 in their bras at the Detroit-Windsor Tunnel.
It's possible in some cases to get the money back, but it can involve months of litigation.
