Ok. then how long it will take for my wife to get green card, after I got mine and fill a petition for her?

Generally speaking, a F-2A application of green card holder for spouse will likely take about 2-3 years if the beneficiary is born in any country other than Mexico (which will take longer). That category just backlogged on the visa chart for April 2023 from being current to being available for final immigration only to those who filed I-130 petitions prior to September 8, 2020. I note that it is possible that the F-2A category can rebound to a more current date in the near future, but that is uncertain.
