Law / I lived in Poland for 5 years then had studies abroad - should I apply for permanent residency or citizenship? [12]

Merged:

Polish citizenship - Karta pobytu or "Zaświadczenie o zarejestrowaniu pobytu obywatela unii europejskiej"

Hi all,
I read similar cases in this forum, but didn't found exactly mine:
I live in Poland from 9 years with wife and 2 kids regular work for all this time,
For these 9 years I did everything (agreements, jobs, credit, bank accounts ....) through a document titled:
"Zaświadczenie o zarejestrowaniu pobytu obywatela unii europejskiej", which i think is not Karta Pobytu,

my question: am I eligible for the Polish Citizenship ? or do I need Karta Pobytu issued from minimum 3 years ?

thanks a lot !
