@makorin , thank you for answering my questions. I understand better on how this situation has evolved.
No, I don't think I would change my earlier articulation. However, I think all you need to do is to amend only the returns ( for form 8938 inclusion ) to the later of (a) when you became a US person and (b) when you became aware of the existence of the account(s).
BTW -- in your first post you mentioned about "interest" -- do you mean that you have had yearly interest earnings that you have not recognized ? If so , you need to recognize these earnings and pay US taxes on these. If the amount is small, it may not affect your tax liabilities for the years that you need to amend.
In any case, please make sure that your future filings are all accurate ( for FBASR, FATCA and interest earnings recognition etc. ). IRS has a habit of flagging and tracking tax payers for at least three years to make sure the taxpayer is compliant.
Hope this helps.
Is there more I can do for you ?
