Divorce does not affect your status you can keep your green card even if your marriage ends.

You can renew your green card normally file Form I-90 when it expires—no need to involve your ex-spouse.

You’ll need to file Form I-751 to remove conditions usually, this is done jointly with your spouse, but you can apply for a waiver if divorced.

You could apply with a divorce waiver if the marriage ended in good faith but didn’t last, a divorce-based waiver allows you to stay.
