The vast majority of undocumented migrants from Mexico were gainfully employed before they left for the United States. Thus, failure to find work at home does not seem to be the primary reason that the estimated 6.3 million undocumented migrants from Mexico have come to the U.S.
The survey findings reveal whether the migrants would vote if they could and which segments of the migrant population are likely to meet key eligibility requirements.
The Pew Hispanic Center conducted an unprecedented survey of Mexican migrants in the United States, including thousands who say they have no U.S.-issued identity documents.
Most Mexican migrants want to remain in this country indefinitely but would participate in a temporary worker program that granted them legal status for a time and eventually required them to return to Mexico.
