Law / How does a US & Polish citizen obtain a Polish bank account? (Without residency in Poland) [4]

I am living in America currently. I do have Polish citizenship with a Polish passport. I just recently got my Polish passport by showing the Polish Embassy my family bloodline history and all of that. My plan is to move to Poland in about 5 years or so and I just want to get everything set up.

So if I am living in the USA and have a Polish passport with me being a citizen of Poland, what's left there for me to do? From what I have read on the internet is that you need to show them proof of residency/resident card. I live in the US and do not live in Poland.. Can I just show them that I live in the USA? Is my USA address good enough? Or does it really have to be a Polish address? Can I give them one of my family members address that lives in Poland?

As the title says.

At which phase of opening is Poland in right now?
