Did you end up solving your problem? I’m in a similar situation: I moved out of USA as of August 2019 for good. I was a resident alien when I left and I no longer have ties to US. Now I want to close my US retirement accounts (it’s October 2019), and Fidelity asks me to fill either W-9 or W-8BEN, whichever applies, and I don’t know which one applies to me. When do I stop being a resident alien after leaving the country? I saw responses to this question on IRS website that could interpreted as “as soon as you leave the country” and also elsewhere on IRS website that seems to be saying “until the year is over”. Asking to anyone who’s reading this, thank you.
