As soon as you have been married, the quickest way to get her to the US is to submit an I-130 petition on her behalf and then request for a K-3 visa on form I-129F. Ideally, requesting a K-3 visa is supposed to shorten the time that a spouse of a US citizen is required to wait overseas for a visa but it doesn't always work out that way. After she enters the country on a K-3 visa, she can submit an application for adjustment of status to complete her paperwork for a green card in the US.
