The law of U.S. citizenship has evolved over time. It can sometimes be difficult to determine whether one is or is not a U.S. citizen. The difficulty has been exacerbated by the fact that in 2004, the United States created (what I will refer to as) the tax citizen.
It is possible to be a U.S. citizen for the purposes of taxation but NOT be a U.S. citizen for the purposes of immigration and nationality. This state of affairs could exist if one had (1) relinquished U.S. citizenship for nationality purposes, but (2) not taken the required notification steps to end U.S. tax citizenship. (It is also possible for one to have lost the Green Card for the purposes of immigration but still be subject to U.S. taxation.)
The difficulty is compounded by the fact that different rules have existed at different times.
For many people who do NOT live in the United States it would be prudent to undertake a careful evaluation of your U.S. citizenship status. This should be done before entering the U.S. tax system.
What follows are two videos of interviews with lawyers Andrew Grossman (2014) and Virginia La Torre Jeker (2018). By watching the interviews you will be introduced to some of the complexities of U.S. citizenship.
