外地 (wai di)- from outside places/soil. Not nationality bound, more a term for migrant workers 'not being from around here'. But using this term suggests some comfort or familiarity with the local place. Otherwise, just state origin.

本地 (ben di)- from local / basic soil. Often used as a badge of pride.

民工 (min gong)- common term for migrant worker in China. Interesting decomposition of the work - 民 (min) meaning a person, or member of the people. 工 (gong) meaning work (with one's hands, literal). This would be the closest match for a European moving country in seek of wage.
