回複：問pjiang等老師們, 拿到綠卡後立即換工作的問題

If you have worked for your current employer who sponsored your green card for more than one year, you can change your job anytime after you get your green card. Nothing worried about. I have known more than ten people changed their job within one months after they got their green card. Some of them have got their US citizenship without any trouble (USCIS did not mention their job change. No immigration law limits new green card holders for change of job once they get the green cards.
