I manage some accounts outside the US. I'm registered with the local government, and not required to register in the US. (As long as I manage money for non-US citizens). But it will help to have some, it makes you look much more professional. So, in order to boost your career and have a more reputable resume: Which exams are relatively easy to pass, without hefty registering fees?
I don't know about the fees but the insurance exam (property and casualty?) has to be easy. Also the series 63 but you might have to reside in a US state. You might wanna go for certified financial planner (is that the one?). I've heard that isn't overly taxing but it will take more time than the afforementioned tests. Really, if you have a few weeks and a sponsor, why not just take the 7?
On the planning front, I had the AAMS when I was a broker as it was so incredibly easy to get and never lapsed. Hell, I still have it now. LOL http://www.cffp.edu/portal/alias__Rainbow/lang__en-US/tabID__3356/DesktopDefault.aspx
No, you have to take it at a testing center in person. Try here for more on scheduling and international test center availability http://www.nfa.futures.org/registration/SO-Sched.pdf
