hhN400

NO! It's not 3 months; it's 90 days in advance. Therefore, the earliest you may file is November 13, 2010. Many people fall into this 90-days versus 3-months trap and their application is rejected because they file a day or two too early.

Added my wife's N400 timeline.
Also, I've taken the liberty of reformatting this into a more readable format by using the fixed-width Courier New font, as the instructions specify.
