Details:
1. Graduated from PhD in May; begun Professor position in July.
2. My H1B Visa is valid from mid 2017 to mid 2020
3. I do not pass the Substantial Presence Test (for e.g. as a graduate student I was treated as a U.S. Resident for Tax Purposes).
4. As a non-resident alien, my "home" country is India.
Since my visa is for 3 years, and the "Maximum Presence" is 2 years, am I immediately excluded from this Treaty?
If not, and I am exempt from with-holding, will I have to retroactively pay back the taxes?
