Separated abroad a long time ago. Filed for divorce. Didn't finalize it (two-part process in the country of divorce - first step is to divorce at the local/regional level. Next step is to register the divorce nationally). Did the first step. Didn't do the 2nd step.
Got married some years later. Want to apply for IR1 now. Flew to country of first marriage. Did the 2nd step, now. Divorce/court documents show current date but with the date of separation of when it happened, which is prior to my current marriage. Can this be used as proof of dissolution of marriage?
