Hello guys,
I'm not sure what kind of adminship are your talking about here. But if you are talking about adminship on Assamese Wikipedia, (sorry if you know that already) you have to request the adminship on the proper page of Assamese Wikipedia (usually the Request for Amidships page or the one you used in past), and need to let it run for no less than 7 days. After that you have to ask for that adminship (permanent or temporary, which kind of adminship that you asked for in local wiki page) on the Meta-Wiki page: http://meta.wikimedia.org/wiki/Steward_requests/Permissions#Administrator_ac... than a steward will process the request on behalf of the Assamese Wikipedia community.
I am pretty sure that current Assamese Wikipedia administrators have gone through the same process in past and they know things better.
