Many people who have come from abroad do not realize the nature and seriousness of the obligation of U.S. citizens and "tax residents" to report to the IRS their worldwide financial holdings regardless of whether they will owe U.S. tax on them, and that they also are taxable in the U.S. on their worldwide income subject to exemptions and tax treaties.
Many people do not realize that tax residents include not only people who have obtained a "green card" for U.S. permanent residence, but also people who have had certain amounts of physical presence in the U.S. without a green card (in temporary status or no status at all).
