United States First Lady Michelle Obama is on a three-day visit to Mexico.

During her trip, Ms Obama will focus on education and economic development. Her itinerary includes a visit to a university and to a primary school. Michelle Obama will also meet Mexican President Felipe Calderón and his wife.

Prior to travelling to Mexico, the First Lady made an unannounced visit to Haiti, which was hit by a devastating earthquake in January. Her surprise visit included a helicopter flight over the affected areas and conversations with victims.

This is the First Lady's first official trip without her husband Barack Obama.
