If you are married and have not been married for more than 2 years then you can apply for a CR1 Visa where you are. This is the CR1 Visa process in order to bring your wife to the United States as quickly as possible.
The process to obtain the CR1 Visa is pretty much the same as that for the K3 Visa application. You first have to file a Petition for Alien Relative (Form I-130) with the USCIS. During this process they will check the validity of the marriage and the relationship of the parties. Once the USCIS approves the application it is forwarded to the National Visa Center or NVC for further attention. Once this has been done the National Visa Center will tell you where to pay the fees for the application. Once the fees are paid they will ask for further documentation. Once this is viewed it will be forwarded to the US Embassy where you wife is located.
It is the NVC or National Visa Center which will setup the date and appointment with the US Embassy for an interview. After the interview at the US Embassy the visa is normally issued within 3 business days after the interview.
