485-RFE-請教皮匠和小白兔

今天收到RFE，信共有兩頁，第一頁很籠統。第二頁比較具體，內容如下：

Submit documentary evidence of all nonimmigrant status granted to you since your last lawful admission to the U.S. on 01/12/99. Please also submit evidence that any and all employement since your last admission has been authorized by this service. Such evidence may include, but is not limited to:

.Copies of both sides of your Form I-94 Arrival/Entry Document;
.Copies of both sides of your Form I-20A-B/I-D (F-1 students and dependents);
.Copies of both disdes of your Form IAP-66/DS-2019(J-1 exhange vistors and dependents);
.Copies of the pages in your passport which show U.S. visas, Service admission stamps or other endorsements, to include the passport identify pages;
.Copies of any and all Employment Authorization Documents (EADs) issued to you by this Service.
最後還有這麽一句話：
Submit evidence after 8/14/06.

請大俠們幫忙回答如下問題：
1。材料到底是限於2006年以後還是1999年以後？
2。這封信是針對主申請人的，家屬的材料要加上嗎？
3。回信封太小，貼到什麽樣的大信封？Priority mail可以嗎？

煩請各位有經驗的朋友指教。
