This number marked an increase from 1,032,600 the previous month, the Statistics Poland (GUS) agency reported.
These foreign workers hailed from more than 150 countries, with 67.3 percent coming from Ukraine, Statistics Poland said on Tuesday.
Belarusians account for 11.3 percent of the foreign workforce, followed by Georgians at 2.6 percent, and Indians at 2 percent. Moldovans and Filipinos each represented 1.3 percent of the total labour force.
An estimated 2.5 million foreigners live in Poland, according to a study last year by the Polish Economic Institute (PIE), a Warsaw-based think tank.
