I would not recommend it. If it were discovered that you were already married when you married in America, you could be arrested for polygamy. If you really want to marry the person, you will wait until the divorce is finalized.
If you were married in the US, regardless of you citizenship, you must get a divorce under US laws. You should go to the US embassy or consulate general nearest to where you live.
The process for the individual trying to gain citizenship will stop.
she is not married she is going out with somebody in middle school
No.
If you live in the US and your husband married you before his divorce was final, then your marriage is not legal. Go talk to an attorney and see what steps you can attempt to take to get it straightened out.
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.
Where you were married does not matter. Follow the divorce laws in your current state of residence.
Yes. If less than 90 days you have to have the final divorce degree. If over you need to know the dates of your marriage/divorce.
The marriage is legal until the divorce is finalized.
If you are married, you can apply for divorce.
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.
If you're in the US, there's no specified length of time. You can get one day and file for divorce the next (unless you live in a state that has a required separation period before you're allowed to file)
