apples and oranges
apples and oranges, dir Sir. you may stay abroad for a year (minus one day, to be sure) with RTD, you may stay abroad for two years (minus one day, to be sure) if you have Advance Parole and more than two years with Advance Parole if you obtained returning resident visa prior to returning.
at the other hand you may go to Canada and decide to stay, get the residence after seven (7) days or in China if you wish, after one day and you'll lose your residence in the USA much sooner than ten, seven or one year. moreover, some have green cards valid for 2 years (conditional resident status) etc.
do NOT confuse people. every situation is different. however, if someone has a valid Travel Document for a year she or he could stay abroad for that year. if someone, at the other hand, want to "cheat" and to "keep" his or her residence in the US while married, employed or whatever abroad that is completely different ball game and he or she should be aware of the consequences.
everyone with RTD, green card, asylum or any other valid immigrant status in the US should use his or her privileges reasonably and without the fear and in
bona fide and it would be no problems whatsoever.
