@DaveF1006 Appreciate your detailed answer. When I claim the tax treaty in my tax returns, should I file Form 8833? Or, is it the exception listed in Publication 519 (page 70), "2.You claim that a treaty reduces or modifies the taxation of income from dependent personal services, pensions, annuities, social security and other public pensions, or income of artists, athletes, students, trainees, or teachers. This includes taxable scholarship and fellowship grants"? Does it mean that I don't need to file Form 8833 because I am a student?
Additionally, can I e-file my tax returns including my 1042S? Or, I have to do it manually and mail the forms?
Thank you very much.
