收到485通知書，有小疑問請教：

１。 485 approval notice上說：Prior to receiving your permanent card, you may be required to report for biometrics processing. If you have not received your permanent card or notice in 90 days, please call customer service. Do I need to do another fingerprint after 485 is approved?

２。收到綠卡能馬上換工作嗎？（從博士後到工業界）

Thanks a lot!
