I got permanent residency in 2020, but moved to the UK (where I am from) later that year and have remained in the UK since. What was my residency status in 2022?

@shaunhamilton87  assuming what you are talking about is I-131, which grants you permission to stay abroad for up to 2 (?) years without  having to enter US , then since your Green card is valid during this period, your tax status is also retained as a US person.  Thus  for the year 2020, 2021 , 2022, 2023 and 2024  you are  a Resident for Tax Purposes  and taxed on your world income by the US.

If your I-131 is not valid and you have not entered US at least once  a year, then  your GreenCard is considered abandoned  and your tax status may become  Non-Resident ( and taxed by the US ONLY on your US sourced income ).

Does this make sense ?

Is there more I can do for you ?
