我是I-485 pending, 用EAD换得工作，现在EAD到期，前两天寄出申请I-765延期。今天收到收据，是这样说的：
“As a reminder, if you have an underlying Form I-140 that is approved or is still pending, you may request to change employers under INA 204(j) if your form I-485 adjustment application has been pending for at least 180 days. In order to do so, you should supplement the form I-485 record of proceeding with documentation relating to the new job offer that forms the basis othe INA 204(j) portability request. ”For more information on how to request to change employer and what information is required to supplement the form I-485, please visit www.uscis.gov."
请问， 是不是让我补充材料才能
1. 延期I-765和
2. 继续申请I-485.
如果是，需要补充什么材料？
多谢了。
