Yes. If the marriage was registered and the divorce was sought in U.S, it is valid. You would be required to secure an original copy of the judgement from the County or District court in the U.S.
Kindly note the problem might arise should either party dispute the divorce given under duress or under criminal intimidation.
Please let me know should there be any further clarification required.
Thanks,
