Genealogy / My Grandfather was born in Poland and migrated abroad - Can I get a Polish Passport? [68]

Merged: Citizen of Poland through grandparents - Confirmation of Polish Citizenship (located in the US)

I'm located in the United States and after speaking with the consulate in my city, it appears that I am most likely a polish citizen through my grandparents (currently only my grandmother is alive). My situation is a little strange though.

1. We do not have copies of either of my grandparents birth certificates and they were lost/destroyed in WWII.
2. They entered the United States using papers from a displaced persons camp.
3. All of their paperwork, including US naturalization papers are consistent in the birth place in Poland.

After downloading the forms and attempting to speak with the consulate (I have no polish language skills right now, and his English was poor), I find myself somewhat lost since I don't have the typical paperwork. Do you guys have any suggestions on what to do or a local polish law firm to help? I'm reluctant to use a polish lawyer because I know nothing about the industry and don't want to get scammed, but it seems like that might be the best way.

Thank you in advance.
