今天受到要补材料的通知如下，
"On May 1, 2007, we mailed a notice requesting additional evidence and/or information in this case. Please follow the instructions on the notice to the evidence and/or information requested. This case will be held in suspense until we either receive the evidence or the opportunity to it expires. Once you the information and/or evidence requested, you will be notified by mail when a decision is made, or if the office needs something further from you. If you move while this case is pending, call customer service."
请问小白兔，射线，一般会要何种材料？雇佣信和工资单？我在两个月内要离开现在的职位，会有问题么？
谢谢！
