Most likely the alien card is considered revoked already. Immigration law says that if you have a green card and live outside of the US for more than one year, your green card is presumptively abandoned. Green card holders are required to reside permanently in the United States, and if you do not live in the US then you may have effectively abandoned your green card.
The person must explore other options to get the green card back, for example, if s/he is married to a US citizen or have US citizen children above the age of 21, a new petition can be submitted to get the green card back.
