Citizen eligibility for a GC holder with a US Citizen spouse

[Naveen898]

I became a citizen on June 2012. My wife got her green card (through her employer) on December 2010. We have been married since 2009.

She will be eligible for citizenship, based on her GC, on October 2015.

However, if we decide to use my citizenship as the basis for her naturalization application, when is she going to be eligible to apply for it? is it June 2015 (3 years after I become citizen) or can she do it before this time? (i.e. 90 days before June 2015 - if there is such a thing)

Which route will be more straight forward and quicker?

Thanks.
