Hi, this answer is super helpful. I'm under the same situation and would like to ask a clarification question. Since the treaty is mentioned by the 1042s, do you mean that I do not need to submit Form 8833 anymore? I didn't realize that there is a Form 8833 before, and I wonder if I have to amend the tax return just because I did not file this form (when everything else is correct).
Thank you
