Despite your divorce from your prior petitioning spouse, if you have removed the conditions on residency properly within 90 days prior to the expiration of your initial "conditional" card, are currently on your permanent 10-year I-551 ("Green Card"), and have now been a lawful permanent resident for a minimum of three (3) years, you are authorized to begin the process of naturalization to obtain your US citizenship.
