Pew Research focuses on unauthorized workers, where they work. It highlights industry where their participation is very high (constrasting with education, where unauthorized workers are virtually non-existent). The figure for agriculture is misleading, in that immigrants, both legal and unauthorized, are concentrated in the produce sector. In California, they account for at least half of produce workers. In construction unauthorized workers tend to be laborers. In hospitality, non customer-facing jobs such as kitchen and housecleaning.
