J1 Tax Treaty for short-term scholar
Hello,
I am now a full-time PhD student at UK. I will go to USA for an internship from 15 July 2008 to 15 November 2008, with a J1 visa of the "short-term scholar" category. I now have the following questions about the tax:
1. Am I exempt from US income tax for the 4-month intern period under the US-UK tax treaty 20(A)?
2. Suppose that I would, after my graduation in July 2009, go to USA again for a postdoc position with a J1 visa. Am I again exempt from the US income tax for the postdoc period, but this time under the US-China tax treaty Article 19 (I am a citizen of China)?
Thank you very much in advance!
Leo
