I've looked into renouncing my US citizenship, but that costs a few thousand dollars. And, the US can reject it for several reasons, one of which is tax avoidance. Also, as per the rumors, it is nearly impossible to get a US Visa after that (and I still have American relatives who I would like to see). Seeing as us expats don't have a senator or congressman, we don't really have someone to fight for us. At least I am still allowed to vote. Before every election that I am eligible to vote in, I email the candidates and ask them what their stance is on taxing foreigners (and don't get me started on the fbar). Based on their response I vote.
