Budapest took the same step against Ziobro's wife, Patrycja Kotecka-Ziobro, Sikorski added.
Writing on social media platform X, the Polish foreign minister said he had received written confirmation of the decision, adding that Hungary had also cancelled the trio's travel documents.
Ziobro, who is currently in the United States, played down the news.
Speaking to private broadcaster Telewizja Republika, he argued that a US visa remains valid regardless of whether the document it was issued against has since been invalidated, and suggested the move should be treated with scepticism given it came from Poland's current government.
Poland's justice minister and prosecutor general, Waldemar Żurek, said his ministry was reviewing the situation and would pursue every legal avenue to bring the two officials before a Polish court.
He added that Poland would ask US authorities whether people without valid travel documents could still legally remain in the country.
On Wednesday, a Warsaw court upheld an earlier decision to place Ziobro in pre-trial detention.
Speaking separately to private broadcaster Polsat News, the former justice minister said he was waiting for an extradition request, adding he would rather face an American court "that is not rigged" than the one in Warsaw.
Ziobro is a suspect in an investigation into alleged irregularities at Poland's Justice Fund, facing 26 alleged offences including instructing subordinates to break the law in order to channel grants to favoured organisations.
He confirmed in May that he was in the US, having spent the preceding months in Hungary, where he and his wife had been granted international protection under then-Prime Minister Viktor Orbán.
Ziobro later flew from Milan to New York on a visa issued to him as a foreign media representative, and was reported to be taking up a role as a political commentator for Telewizja Republika.
Romanowski, who also faces charges in the Justice Fund case and is the subject of a European arrest warrant, was granted protection by Hungary in December 2024.
His current whereabouts are unclear: he left his Budapest flat in late May, and Polish media have since reported sightings in Serbia and Croatia.
Serbia's chief prosecutor said in late June she was willing to cooperate with Poland on the case but could not confirm whether Romanowski was in the country.
Hungary's Prime Minister Péter Magyar said, both before and after his election victory, that Budapest would not provide shelter to people wanted by the international community.
