The article seems to imply that renouncing citizenship isn't that easy; particularly, they will still want you to pay back taxes.

I imagine that if you were born abroad you might not realize that you ever need to submit any tax documents to the US, and then I'm pretty sure they will want to collect money before allowing you to renounce.

Renouncing citizenship is not unilateral in the US, unlike some countries. The US state department has to agree to it. And you have to realize that you have to do it, of course.

I agree that the law is there for a good reason, obviously. but it can lead to people having US citizenship without even realizing they have it.
