Some weeks, José Edgardo Andrande makes less than $200. Other weeks, his pay tops $1,200. "But then it goes down to $500" the next week, said Mr. Andrande, 42, a job hopper from El Salvador who, for 24 years, has worked as a delivery person, electrician, restaurant worker and builder in the United States.
Despite the changes, one financial transaction has remained the same. Each month he sends $700 home to support his two sons and mother in his native San Salvador.
