How immigrants without bank accounts get by

An introduction to “unbanked” workers in America – mainly Mexican – can be found at Financial DNA Weekly, May 14, 2004 According to this report, the Mexican worker in U.S. remits on average $2000 a year to Mexico. Average individual remittance is $300, with transaction fees of $10 to $20. This is a $3.5 billion business growing to $10 billion. This source estimates that only 25% of Mexican workers have a bank account, which presumably supports its $10 billoin forecast.
Another source, in contradiction, estimates that 40% of Latin American in the U.S. do not have a bank account. “A worker earning $12,000 a year could pay $250 for check cashing services” per Banking the Poor: Policies to Bring Low-Income Americans Into the Financial Mainstream, by Michael S. Barr, University of Michigan Law School, Published in The Brookings Institution, Research Brief, pg. 1 (September 2004)
Jopari Solutions, run by insurance professionals, has reportedly proposed to major workers compensation insurers a service to expedite indemnity payments, including to unbanked recipient.
