First of all, I think that you need to have this in the immigration section----perhaps it's already there because of the tag. However, I can't help but get the feeling from you that you view marriage as your "passport" to the States. I mean, if you have a legitimate marriage to someone that you truly love and live with that is one thing. But your current marriage sounds suspect, too. Where is your home country? Did you ever live with your current wife? I don't know what the authorities will think if/when you get divorced and try to marry an other U.S. citizen, but I would have to think that there would be additional scrutiny. And please don't take this personally, I don't know you and maybe all of this is legitimate. It just sounds very suspect from my perspective.
Please be advised that any answers or information disseminated above do not constitute legal advice and that the attorney responsible for this posting is merely attempting to participate in a Q & A session intended to be helpful but certainly not intended to be legal advice. It is important that you understand that no attorney-client relationship has been formed and that the attorney has no obligation to follow up with you with your legal issue unless you separately contact said attorney and arrange for him to legally represent you.
It may be an issue but as no petition or application has been filed on your behalf with US immigration, it should not cause a denial for a future application.
The answer provided here is general in nature and does not take into account other factors that may need to be reviewed for a more precise answer. You should consult with an immigration attorney before taking any action. The answer here is not intended to create an attorney-client relationship.
The fact that you do not apply to immigrate to the U.S. based on your current, failed marriage can work to your advantage. It shows your primary interest is in the relationship itself and not in the green card. In the future, you will have a bit of a messy situation to explain if you marry a different U.S. citizen and want to immigrate. At that time, you should consult with an immigration attorney who can help make clean filings and put you in the best light.
