Reentry Permit and N-470
Any lawful permanent resident (LPR) or a conditional resident (CR) must present an admission document like special immigrant visa (obtained at consulate abroad), green card or reentry permit upon entry to the U.S. after their temporary trip abroad. In the absence of such document he/she is considered inadmissible. If the LPR or CR seeks admission to the U.S. after more than one year since her departure from USA, the green card may not be sufficient to allow them back into the United States.
