Most current Polish requests involve civil, identity, legal, and academic records issued in Poland for immigration and official U.S. use, and Polish birth certificate translation remains one of the most common packet types.
Poland is a Hague Apostille Convention member, and under the HCCH status table the Convention entered into force for Poland on 14 August 2005 after accession on 19 November 2004, so Polish public documents generally use an apostille instead of embassy legalization when the receiving country is also a Hague member.
That apostille step does not replace certified translation: USCIS, courts, and universities still require a complete English translation of Polish names, diacritics, seals, annotations, and akta stanu cywilnego field labels.
If you are relying on an older original, a reissued civil copy, or filing in a non-Hague destination, confirm whether you need translation only, translation plus apostille, or embassy legalization before submission.
