I am an international student from China and currently am a resident alien in Baltimore MD. I got salary from my school in Baltimore every month. In summer 2019, I worked as an intern for a company in NYC for less than 3 months. I was wondering 1. Federal tax form , NY state tax form and MD state tax form. Are these three forms all forms I need to fill for my tax return? Is there any particular order I need to follow to avoid double state tax on same amount? 2. Am I a non-resident alien for NY state tax return? Which form should I fill for NY state tax? 3. For the money I got during my intern, do I need to pay tax for this income to MD? 4. I also would like to claim China-USA treasury for student. Which product should I use? Thank you in advance for your help.
