1. 照片背面要写名字和一个Number，Instuction上说是Alien Receipt Number，请教是指Form I-797A上的I-94#还是Receipt#（EAC-xx-xxx-xxxxx）？
-Not need because you don't have it.
2. 要递交护照上H4 Visa Stamp pages吗？
我护照上只有前一个公司申请H4时的Stamp，后来先生换工作，新公司又给申请了一次，就只有I-797A了，我需要寄护照上的Stamp page 吗？
-Yes, and the H-4 I-94 with the H-4 aprpoval notice. Read these links:
