Are permanent residents free to travel to and from the US at will without regard to time abroad? Are permanent residents free to travel to and from the US at will without regard to time abroad?

Only US citizens may depart the US for extended periods and return to recommence an open ended residence. While permanent residents may travel internationally, they must retain their intention to maintain their primary residence in the US. Demonstration of this intention may be undermined by extended absences abroad, purchase of residence property in another country, or taking foreign employment, for example. It is not sufficient to simply return to the US once a year. Permanent residents anticipating an extended absence from the US of up to two years may secure a reentry permit which preserves status while away and may be used to reenter on return.
