Get an officially translated birth cert and make sure it has the crossed L [£]
Thanks! Yep, managed to find a translator who'd do it (for the marriage cert, and that was only accepted because it was supported by the cert of no impediment from the British Consulate - 500 frickin zloty) but the USC don't want to accept it. Like Ben
says, it has to match up exactly...
Naturalization Records might have both versions. Just a guess.
Well, that's the next step but I'm reluctant to use more documents than necessary - the more you give these people, the more reasons they have to delay things and cause problems... Still, it might be the only way.
So I absolutely must have a PESEL?
