Nawrocki is scheduled to visit the US capital on Sunday at Trump's invitation to attend UFC Freedom 250, a mixed martial arts event being held at the White House to mark the 250th anniversary of American independence.
The event also coincides with Trump's 80th birthday.
Marcin Przydacz, who heads the Polish president's International Policy Bureau, said Nawrocki and Trump would hold talks on security, bilateral relations and economic and energy cooperation.
"For us, the most important issue is, of course, security policy and the presence of American soldiers," Przydacz told reporters.
He added that Nawrocki would raise the issue of establishing permanent US military bases in Poland.
"The Polish president will have an opportunity to advocate Poland's most important interests in a direct conversation with the president of the United States," he said.
Przydacz described relations between Nawrocki and Trump as "very good" and said the White House visit would further strengthen both bilateral ties and the personal relationship between the two leaders.
He argued that direct presidential contacts currently play a central role in relations between Warsaw and Washington, suggesting that Nawrocki has greater access to the Trump administration than Poland's government.
He told reporters that time had been set aside for discussions between the two presidents on Sunday, though he cautioned that schedules could change.
Nawrocki is also expected to meet with members of the Polish American community during his visit and attend a church service outside Washington, possibly in a southern US state, Przydacz said.
The Polish president will bring Trump two gifts, one personal and one official, though no details were disclosed.
The prospect of a permanent US military base in Poland has been discussed for years as Warsaw seeks to deepen security ties with its most important NATO ally amid concerns about Russia.
Last week, Defence Minister Władysław Kosiniak-Kamysz said he had formally proposed the creation of a new permanent US military base in Poland during talks with US Defence Secretary Pete Hegseth.
The proposal came amid discussions about the future deployment of US forces in Europe. Kosiniak-Kamysz said Hegseth had assured him that no decision had been made to reduce American military capabilities in Poland.
Trump later announced that the United States would deploy an additional 5,000 troops to Poland, saying the decision reflected his relationship with Nawrocki, whom he endorsed during Poland's 2025 presidential election campaign.
Nawrocki previously visited Trump in Washington in September last year. During their White House talks, Trump pledged to maintain the US military presence in Poland and said it could be expanded further.
Trump also reaffirmed US security guarantees for Poland, highlighted close military cooperation between the two allies and invited Nawrocki to attend this year's G20 summit in Florida.
