The experience of Mexican nationals who send money home from the United States forms the basis for this study. The authors identify three stages of the remittance process: the First Mile, when decisions are in the hands of the remittance sender; the Intermediary Stage, comprising systems that facilitate the cross-border transfer of funds; and the Last Mile, where the funds reach the hands of the remittance recipient. This analysis, covering the last eight years, may provide guidance for other remittance sending and receiving countries that seek to encourage formalization of the flow.
