@pk Namaste to you too and thank you for your response.
Actually, you confuse me more. Please forgive my ignorance, as per this page when calculating substantial presence for 2020, it is said to consider only one-third of days of 2019. Hence, as per my calculation, for 2020 I was present 70 days, in 2019 I was present for 6 months so one-third is approximately 60 days and I was not present in 2018 at all. So, 70 + 60 + 0 = 130 which is much short of 183 required. Hence I am confused whether I should file 2020 taxes as non-resident.
Thank you.
