good job on saving!
I know this from multiple sides. since US kept sueing Swiss Banks and putting on harsh rules about tax evasion, noone wants to have US citisens as customers anymore. too bad 
I guess IB will be your first choice for investing. The questionaire should not be a problem. nobody here put in a realistic value in “how many transactions did you do so far” question^^
Or, if you as a US Citisen could set up an account with Vanguard directly, this would be your best bet?
Anyway, you clearly want to put your cash at work instead of idling around.
this is quite nasty as you fundas are locked in there. Try check out this thread on how to get you money out
