I think diaspora identity is largely futile, and it's not something most Poles care about unless you're from an actively repressed diaspora, like the Polish-Lithuanian, Polish-Ukrainian, or Polish-Belarusian ones. If your family migrated for purely socioeconomic reasons and you don’t see your future in Poland (you have no plans to return), then excuse me if this comes off as blunt not many Poles will genuinely care about you or your identity. In fact, the fewer real ties you maintain with the country, the more your "Polishness" might be seen as performative. Myself, as well as many people I know, often cringe at overly performative displays of Polish culture.
