@adi47 the purposes of the "address in the USA" is for the IRS to update IRS records on an exempt individual and therefore if you are filing the 8843 in 2022 to correct "non-filing" of the forms for the years 2018, 2019, 2020 then that address should be your address in 2022 at the time of filing. I am assuming here that for the 2021 you are filing the form 8843 along with your return in filing season 2022.
That that help ?
