About Filing Form 8833. If I am a student (also resident alien) who claims the tax treaty, do I need to submit form 8833? From the second item of "exceptions" on the website (https://www.irs.gov/individuals/international-taxpayers/claiming-tax-treaty-benefits), it seems that the income of students belongs to one of the exceptions. Does it mean that I do not need to submit Form 8833? Thank you.
