祝賀！也請教個問題

幫忙看看：我的綠卡申請到了這步：the results of your fingerprint review for your I485 Application to Register Permanent Residence or to Adjust Status were received, and processing has resumed on your case. We will mail you a notice if further action is needed, or when a decision is made.
以你的經驗，要多久才能拿到綠卡？非常感謝！
