Age problem for USA citizenship?

My aunt(mother's sister) live in usa. so my mother applied for us citizenship about 10 yrs ago. Now they have accepted the application and already sent the file in bangladesh emby.from there they are suppose to call us. i heard that there is a serial number, on the basis of which they call people. Now my age will exceed 21 in august 2009. is there any official way that i can make them call us before august 2009? what can or what should i do now?
