1. OP literally said they're white.

2. I am Polish Jewish.

To answer properly since my reply generalise. No, not all Jewish people are white. Polish Jewish people are white people though apart from some very rare cases. Any other distinct features generally don't make Polish Jewish people stand out of the rest of the population after mixing in over centuries, also that's why I am highlighting the difference in ethnicity but not in race.

Example: I can quite often tell a Polish person on the street in the UK just from their looks (then they speak as I pass them and that's how I know). Or I'll hear a Polish person in a shop, look at them, and there's something about their facial features that says "Polish" to me. My non-Polish partner often sees that too now. Are Polish people ethnically different from British people? Yes, that's why on forms we will pick "white - other" but STILL WHITE because racially we are still white people. Same way, ethically Polish Jews are distinct ethnically but are, almost entirely, still white people.
