Because you are now physically present in United States, you can file for green card, but then only when your I-130 priority date becomes current. You CANNOT start processing your I-485 green card application until when your priority date is reached. Finally, you should not work or violate any of the terms of your F-1 student visa. If DHS determines that you violated your F-1 status, it will deny your I-485 green card application when it is eventually filed.
