我的I-485現在的狀態是Initial Review, 哪位已拿到綠卡的哥姐

弟妹們能告訴我，離拿到綠卡還需多少時間？我有空卡，丟了工作是不是還能再呆在美國找工作？謝了！

Initial Review:
During this step, USCIS initiates the background checks of the applicant/petitioner and identifies issues that may need to be addressed either during an interview or by asking the applicant/petitioner to submit additional information or documentation. USCIS reviews applicant's/petitioner's criminal history, determines if there are national security concerns that need to be addressed, and reviews the application/petition for fraud indicators.
