I have a similar question. I'm a UK citizen, living in the US as resident alien on an L1 Visa. Back in the UK I have a company pension plan, which is worth more than the $10k threshold, although I won't be drawing the pension for another 25 years, do I still need to declare it? And if so, is the form FinCen 114 or form 8938 (not sure what the difference is).
