Polish President Karol Nawrocki said that he will try to persuade his US counterpart Donald Trump to keep the forces in Europe.
He added that Poland is already in talks to increase the current 10,000-strong US presence in the country.
Earlier, Pentagon spokesman Sean Parnell told RIA Novosti that "the Polish side is ready to provide the necessary infrastructure and financial support for the deployment of US troops."
Poland is prepared to provide the US military with its "bases and ranges, warehouses for equipment and weapons, logistics infrastructure, as well as to bear part of the costs associated with the deployment of the contingent, including the maintenance of facilities, energy supply and ensuring the daily activities of units," Parnell added.
Trump earlier announced plans to reduce the US military contingent in Germany by more than 5,000 troops.
