回复：如果老板不能帮助办理绿卡，H1B可否转换工作

Find a new job, and ask your new employer to apply H1 for you. Keep your current job until you get receipt of your new H1 application. You can work for your new employer as soon as you get receipt, but for safe reason, it may be better for you to work in your current company until your new H1 get approved.
