Does anyone know any good tax lawyers who are well versed in the issue of Canadian and US tax laws? I have a Canadian friend whose husband is an "accidental American" (born in the US but has never lived or worked there). He believed he'd renounced his citizenship in 1982 as the rules at that time were that applying for other citizenship (Canadian) renounced US citizenship. He's now being told he's still an American citizen and may be subject to penalties as high as $10,000 per year per account because he wasn't declaring every single account he has (because he didn't think he was an American of course). They can also ban him from entry into the US because he doesn't have a US passport (only a Canadian one) which affects his ability to run his company. The whole thing sounded a bit far fetched until I read stories like this: "The attack on accidental Americans" (http://mises.org/daily/5666) and this "Expats call for FATCA repeal" (http://www.forbes.com/sites/robertwood/2011/09/06/expats-call-for-fatca-repeal/). Anyone have any experience or knowledge surrounding this? What should they do now?
