How do I get divorced if I got married in Mexico?
Yes, you can get divorced in the US and would have to do it in the state where you are residing. Just contact a family law attorney in your city/state. Many of them provide initial free consultations. You will lose your H-4 status once you are no longer married.
Can we get divorced in the US if we were married overseas?
Yes. You can divorce in an American state even if you were married abroad. However, you can't file for divorce until you fulfill your current state's residency requirements, meaning that you have to live within that state for a period of time prescribed by the state's divorce laws.
Can you get married in another country and still be legally married in the US?
In general, marriages which are legally performed and valid abroad are also legally valid in the United States. Inquiries regarding the validity of a marriage abroad should be directed to the attorney general of the state where you live. American diplomatic and consular officers are NOT permitted to perform marriages.
