An Advanced Parole is issued to an alien who does not have permanent resident status. A Re-entry Permit is issued to a permanent resident of the U.S. The two documents are dissimilar in physical appearance: an Advanced Parole is a single piece of paper bearing the alien's photo, whereas a Re-entry Permit looks like a passport.

An Advanced Parole functions like a visa to the U.S., while a Re-entry Permit functions like a passport. In another words, an alien with an Advanced Parole still needs a foreign passport to enter into the U.S., while a permanent resident with a Re-entry Permit does not need a foreign passport to enter the U.S.  Another difference is the duration: Advanced Parole is valid for one year, whereas a Re-entry Permit is valid for two years.
