Thank you for linking, correct I am referring to filling out a form and filing it with the IRS/Financial Crimes network under the Foreign Account Tax Compliance Act (FATCA), which is discussed in the linked article. However, the annual filing requirement under FATCA I believe is a separate rule from declaring an asset when crossing the border (the main discussion in the article). Again, so many burdensome and overlapping rules and so little guidance to legally comply :( .
