Can a green card be revoked?

if someone is already illegally staying in the U.S., then find a loophole surrounded by the immigration law and obtain his green card in his original country, will this person's green care be revoked once his illegal status is revealed?
Answers:   
Yes, any fraud is grounds for revoking his green card. Even if he gets US citizenship, and then the fraud is discovered, his US citizenship will be revoked.

What is the loophole?

Green cards can be revoked, but people who be once illegal can still get green cards once they go through officially recognized channels.

In this persons case, if he lied or commited fraud to catch the green card it can be revoked.

However if he told the truth about being here illegally and a waiver be granted then he could now have a valid green card.
Yes, it will be revoked.
