I'm a graduate student and I receive a fellowship in the form of a stipend from Mexico to help pay for living expenses and health insurance. I entered the United States as a nonresident alien, but am now a resident alien for U.S. tax purposes.
According to publication 519, it is not 100% clear if I need to report this as income or not: "How to report income on your tax return. In most cases, you will not need to report the income on your Form 1040 or 1040-SR because the income will be exempt from U.S. tax under the treaty." (p.47)
Question: does Mexico have a treaty for fellowship grants? Does the tax treaty saving clause provide an exception for it? Does it have a time limit? In short, what should I do?
