Time for naturalization

[RRRLAM]

Hi all;

Can you advice me when I can apply for naturalization ? I have a confussion. I jut got a 1st green card and it is a 10 year green card, permanent residence since Feb/20 and expire Feb/30. I married in Jan/18 and submitted an application in Feb/18. Do I have to wait 3 year since Feb/20, which means Feb/23 to apply for citizenship ? or I can apply for it in Oct/20, 3 months before the anniversary. I marry a us citizen

3 months before your 3 year GC date, so Nov 2022. Just be careful that you apply that 90 day window and not on day 91.
