What if my trip abroad will last longer than 1 year?
If you plan on being absent from the United States for longer than a year, it is advisable to first apply for a reentry permit on Form I-131. Obtaining a reentry permit prior to leaving the United States allows a permanent or conditional permanent resident to apply for admission into the United States during the permit’s validity without the need to obtain a returning resident visa from a U.S. Embassy or Consulate abroad. Please note that it does not guarantee entry into the United States upon your return as you must first be determined to be admissible; however, it will assist you in establishing your intention to permanently reside in the United States.
