Trying to locate archive copy of grandfather's Polish passport

My grandfather emigrated to the US in 1926 at the age of 15.

I'm trying to confirm PL citizenship. I've found his birth certificate (through a cousin going to archives in Gruszowiec) and baptism records, but I'm not sure where to ask her to go to look for an archive copy of the passport.

Would anyone happen to know where this could be found?

Thanks in advance!
