@Japtrupusz , US tax rules are the same for all US persons ( citizen / GreenCard) -- whether one is residing in the USA or abroad -- to maintain GreenCard valid one must enter US at least once a year ( unless dispensed by Immigration authorities). As a US person, one must still tax return, and comply with FBAR and FATCA regulations just as if one was living on mainland US or its territories.
Does this answer your query ? Is there more I can do for you ?
