How long does it take to get a divorce after getting a permanent green card?

You can get divorced if you go to the United States with someone who holds a U.S. green card.

If you have obtained a green card and divorced, the green card is still valid, but do not arouse the suspicion of the Immigration Bureau. If the Immigration Bureau suspects that the green card was obtained through illegal means, it will cancel the green card qualification and leave the country within a time limit.
