Dear Forum Team,
Is it possible for a person to be denied entry to USA on a valid Green card after an absence of more than one year.
Sincerely,
Melodie

Certainly... under current rules being out of the country for over a year is considered abandoning your immigration atttempt. THe rules changed because too many people were getting them as a convienience but staying elsewhere, depriving others who actually wanted to be here a chance.
