The supporting evidence that you would file would be birth certificates, marriage certificate, divorce certificates if either of you have been married previously, proof of your U.S. Citizenship, proof of your spouse's legal entry into the U.S., and financial documents to prove your income over the last year at least.
In about 3 to 5 months after filing, she should get a work permit. About 5 to 7 months after filing you should get a marriage interview. If all goes well, a few weeks later she should get a Residency status (green card). Please let me know if you have any additional questions. I would be happy to answer them for you without additional charge. My goal is to provide you with top-notch service - please don't forget to leave me feedback if that is available for you to do so and a bonus is always appreciated.
