You have to be in US more than 1 year before sending your application to Buffalo, otherwise you have to apply in Beijing even you are in US. The total processing time in Buffalo is around 1 to 1.5 years based on your case (with or without interview, when will you send police certificate, etc), therefor total 2.5 years is general.

Please read post carefully before post any wrong information.
