I'm not totally sure what exactly you're asking- it sounds like you're asking if the US recognizes a legal marriage from Mexico.
If that's the case, then yes, the US does recognize legal marriages that happen in other countries- it actually happens all the time, people get married at resorts in Mexico, Jamaica, and elsewhere in the Caribbean, even occasionally on cruise ships! This of course requires that the marriage was properly registered with the relevant local authorities.
So you cannot legally marry another person until the Mexican marriage's divorce proceedings have finished.
He is guilty of bigamy. You can start the divorce process.
My spouse has filed for divorce; we live in IN and he is travelling to Mexico with his other woman. Can he legally marry her while in Mexico?
Yes.
No, you can file for divorce in whatever jurisdiction or country you are currently living in.
i got married 2 years ago in las Vegas with a british citizen, i am from Mexico, we also got married on the church but in Mexico how can i get a divorce if i married in las Vegas but i have 1 year living in Mexico?
You file for divorce in the state where you are a resident, which may or may not be the state where you married.
No. I don't think it would be legal. I know people go to Mexico for divorce, but there is special paperwork and requirements that they meet. But, if you wanted to go to Germany for divorce I don't think you could. The laws there are German, not American law.
No, in most countries it is illegal (a crime) to marry someone that is still legally married to another person.
Yes, I did it in Texas
Usually a person files for divorce in their current resident state. If your Mexican marriage is recognized as legal by the U.S. then you will have to file in America if that is where you are living
He is already married, you can't marry him unless he gets a divorce.
If New York is where you reside- yes.
