90 days. 3 year. Within or on the exact date?

We have the 3 year window for the N400 on September 4th, 2015. Do we have to apply on that exact date or can we apply later during the month? Paying for this thing take some budgeting so I just want make sure. Also, if we don't apply now... can we still apply later with the 3 year rule? or do we have to wait 5 years?

My husband is PR. I am US citizen. We have close to 5 years married. HIs GC 3rd year anniversary in on December 3rd. I used the N-400 calculator and I get confuse because it says "the earliest you can apply" does that mean we can apply later? For example, September 20th or October 2015?

Yes - you can apply later. there are people that never apply at all and continue being permanent residents for the rest of their lives.

You are eligible for Naturalization 90 days before your 3 years green card anniversary base on your marriage to a US citizen or 90 days before your 5 years green card anniversary base on your permanent residency. You do not have to apply on the exact day of your anniversary or within the 90 days, you can apply 1 day, 1 year, 4 years...later it's up to you once you are eligible. I applied 6 months after I became eligible. By the way I'm originally from Cameroon. Good luck to you guys.
