Agriculture still leads in undocumented workers…
Check this out:

The share of all unauthorized immigrant workers with management and professional jobs grew to 13% in 2012 from 10% in 2007 — an overall increase of 180,000, according to new data from the Pew Research Center.

“In a reflection of changes in the overall economy since the Great Recession, the U.S. unauthorized immigrant workforce now holds fewer blue-collar jobs and more white-collar ones than it did before the 2007-2009 recession,” Pew says.

Despite these advances, undocumented workers’ representation among all white-collar occupations remains low — just 2%. Agriculture has replaced construction as the industry with the largest share of undocumented workers.
