Mexico is reportedly testing out a pilot program that would require foreigners who enter Mexico for more than seven days or who are involved in paid work there to pay a fee of 306 pesos, or about 28 American dollars.
As of now, the fee only applies to pedestrians who cross into Mexico through the ports of entry in Otay, San Ysidro/El Chaparral, or Puerta Mexico Este. Vehicles are not yet included.
"Foreigners who enter Mexico have the obligation to register; if they will be in national territory for more than seven days, they have to pay the right of non-residents," said Rudolfo Figueroa, a representative of Mexico's National Immigration Institute.
