I’m researching whether my grandfather retained Polish citizenship under the Polish Nationality Law of January 31, 1920, and I’d like to get advice from people with experience in Polish citizenship law, especially in historical contexts.

Facts:
- Grandfather born in Poland in 1903.

- He Poland in the last quarter of 1920 — I have U.S. arrival records for both November and December of that year. (one coming from Canada, one coming from Poland)

- He was under 18 when the 1920 Polish Nationality Law came into effect (31 January 1920).

- Married in the U.S. in 1929, naturalized in 1931. Father born in 1934.

Questions:

- Under the 1920 Polish Nationality Law, would a minor (under 18 ) automatically retain citizenship if his father was residing in Poland on 31 January 1920, even if the child left Poland later that same year?

- In such cases, is it necessary to prove the child’s residence in Poland at that exact date, or is it enough to prove the father’s residence in Poland on that date?
If the latter, what forms of evidence are typically accepted by the Polish Citizenship Office? Which ones are easiest to obtain from Polish Archive?

Potential complication:
- All U.S. records list his place of birth as CITY A, about 70 km from CITY B, the town recorded on his official Polish birth record.
- CITY A was about 3x larger in population than CITY B. I believe he genuinely did not know he was born in CITY B. Could this discrepancy cause the Polish Citizenship Office to question the record, or is it common for emigrants’ birthplaces to be recorded as a nearby larger town?

Related issue about my father:
- My father (grandfather’s son) was born in 1934, meaning he turned 18 in 1952 — after the 1951 Polish Nationality Law took effect.

- Given that timeline, he could not possibly have served in the U.S. military before 1952. Would the Citizenship Office still require “proof of not having served,” or is the impossibility due to his age under 18 prior to 1951 generally accepted without documentation?

Any guidance on the evidentiary standard for residence in 1920, how strict the birthplace detail needs to be, and how the military service requirement is handled would be greatly appreciated.

Thank you.
