What do you mean 'international'? I just went to Urząd Stanu Cywilnego and asked for a complete copy of my birth certificate (just in Polish), and then for something else got a shortened copy which had the features I mentioned to you, but they are both on the same form, orange in colour, and I think they are standard for Poland, it's just that the second one is issued, like our passports, in 2 languages. Are you suggesting then, that I also have to have my passport translated, even though it's in Polish, English, German, and French? Did you get your wife's birth certificate translated? (I did myself, just in case, but a year ago, and was wondering if, on my next visit, i should get another one with a more recent date and a more recent translation, or would that two-language one be enough)?
