Will I lose my green card status after divorce?

Hello, You may  lose your green card, not necessarily because of the divorce (for it sounds like you have been married for a long time to your US citizen spouse) but because you will no longer live in the U.S. The reason for this is that as a legal permanent resident you are required to live in the U.S. You may choose to become a U.S. citizen before you move and be able to travel freely back and forth, or you may move back and understand that you will be coming back to the U.S. as a visitor when you no longer have a green card.  Good Luck.
