Lola: Assuming you had a legal marriage, regardless whether in Turkey, UK, etc., yes, your marriage is valid and recognized in the US,just like Turkey would have recognized the marriage if it had taken place in the US, UK,etc. Even if marriage was not registered in the Estates, you are legally married so ensure you do not remarry without divorcing first, if you do, you would be committing bigamy.

You do not have to go to Turkey for a divorce, you can file from the US and obtain a judgement from an American court, especially since you have no intent of returning to Turkey. Try expertlaw forum, this might be more suitable to your needs. If you are considering an annulment, this would be way more expensive, difficult to prove and lenghty so just file for divorce.

I too married a Turkish man (in Turkey) and filed for divorce in the US without any problem. He was deported
from the US for visa fraud.

Good luck.
