@malhotra , The six year rule which applies to J-1 ( trainees-teachers , non-student , etc. persons ), generally allows exemption if and only if during the previous six calendar years one is NOT an exempt person for during any part of two years i.e. 2 out of six. SprinTax has applied the rule including the first two years ( 2009 and 2010 ) when you were J-1 -- Non-Student for a few months each year. By this correct analysis, you are Exempt for the Calendar year 2019 and for the Calendar year 2020 ( absent any status change). If you were not to apply the six year rule for J-1 Non-Student persons, then your original J-1 X 2 plus F-1 x5 would suggest that 2014 on wards you would be Resident for Tax purposes. It may be to your advantage to follow SprinTax path.
