EB-1A I-140 （self-petitioner）获得了批准。Form I-485 Instructions中有这样的文字：
“If you filed Form I-140 as a self-petitioner, you must intend to work in the occupational field specified in the Form I-140. You must provide a signed statement confirming this intent, unless you are filing Form I-485 together with your Form I-140.”
现在准备I-485. 我的employer UPDATED employment verification letter (含job title, salary, and responsibilties). 这种情况下，还需要这signed statement吗？ 如果需要， I-485只是要求signed statement， 还是需要进一步公证？
另外，EB-1A的I-485需要PAY STUBS吗？
很多问题， 不好意思。多谢帮忙！
