"Typical american response?" How about, typical polish pretentiousness... i'm giving valid information and you are striking down facts?
Facts according to who? You're talking about "playing it safe" and all this other rubbish.
Take a look here - newcitizen.us/losing.html - can you see anything there that suggests that you can lose US citizenship for not paying taxes? Nah..didn't think so.
Are you a US citizen? Do you know that US naturalized citizens have to swear an oath to renounce other citizenships? Or did you allow yourself to "not notice" it because it was just a "typical" american document that meant nothing to you?
What has that got to do with your situation? You're not a "naturalised" citizen, therefore it's a moot point.
For people who have dual citizenships, I think it's important to know how to behave at the border, to identify yourself appropriately, to file your taxes, etc. I want to know the ins and outs, so that when policy changes in the future (and it can), I will have done everything correctly.
And tell me - how do you think the American Government will find out about your Polish passport?
Needless worrying/scaremongering, that's all.
