You can submit your Naturalization application 90 days before the 3rd anniversary that you were granted Permanent Resident status (the date on your GC).
True, but only if you meet all the other naturalization requirements. Kirts timeline looks like a CR-1 visa. Note that, in order to be eligible to submit the N-400 90 days before the three year application, you must have been living together in valid marital union for
three full years on the date you file the N-400.
For someone who got a green card via adjustment of status, there's normally no issue -- they were living together for well more than three months before LPR status was granted. But for a CR-1 case, they may not have been living together until the day the alien arrived in the US with LPR status.
The requirement is stated on page 22 of the M-476 as "You may send your application before you have met the requirement for continuous residence only. Therefore, you must still have been married to and living with your U.S. citizen spouse for 3 years before you may file your application." The law has slightly different language, and the regulation has still other different language, and the published interpretations put a different slant on things. I'm not sure how literally to interpret the "and living with" phrase in the M-476. I don't know the final answer, but the subject has been discussed in considerable depth on
this VJ thread.
