thanks for the advice rotorhead...
in terms of my situation, it is fairly direct and simple, just my salary and the account it is being direct depoited into, even that I don't keep much there, I transfer everything to the states immediately... I prefered to use the US address for mail reliability and simplicity, but I will probably seek the advice of an expert just in case regarding the address issue.
I prefer to use TT cause it is reliable and simple, and even when I did get audited a few years back, they took care of everything... stressful, but got a clean bill of health...
