@yk6 what visa did you come in with ? When did you enter the USA and how many days/time did you spend in the USA during the years 2018, 2019 and 2020 ? Are you still working for the same employer as in 2020? Which country are you from ? Did your employer withhold federal, State and FICA taxes the whole of 2020 ( even when you were working remotely ) ? Did you have to pay any taxes to your home country for the period that you were away from the USA ( i.e. during the year 2020 ) ? Are you married and if so was your family in the USA all through 2020 ?
