Will it be a problem to get green card if I dont have job and Will I be able to travel out of country...

Your current unemployment will not prevent you from obtaining a green card through marriage to a US citizen. However, you should consult with a knowledgeable immigration attorney to ensure that are no other issues with your qualification for a green card.

Just because it is printed on your visa does not mean you are not subject to 212(e). Consuls make mistakes. Only an advisory opinion from the US Department of State can definitively determine if you are subject or if you are not. If getting a green card is important to you, you should consult wi an immigration attorney.

This issue is a problem: You should apply for a "next-of-kin"/finance visa. In all liklihood you will have to apply at an embassy or consular office in your home country (that means you have to go there, because they interview you). After you have married--either before or after you re-enter--you will have to apply for re-classification as a green-card holder. Your overstay will present factual issues. You do need a lawyer--run, do not walk! By the way, once you leave the country it is unlikely you can re-enter in any other status that fiance.
