application for citizenship

The three-year rule for citizenship from marriage to a US citizen contemplates that the applicant will either have been a conditional or green card holder for three years, that the US citizen has held citizenship status for three years, and that the couple have been living together on a constant basis for the three years. Under those circumstances, an application can be made 90 days before the three-year mark as long as only the first condition is at issue. If the green card that you received is your first green card and you did not receive a conditional card previously, you would have to wait three years. If you previously received a conditional card, the time to start counting for citizenship would begin with the award of the conditional green card.

You have to be a permanent resident for 2 years and 9 months before you can apply, and that period of time has to overlap your marriage to a US citizen.  In other words, you'll have to wait 2 years and 9 months from the date the card was issued, not the date you got married.
