查看了申请时律师叫我准备的材料：

1. Complete questionaires
2. Submit Payment for Attorney Fees for Praocessing
3. Compile and Forward Supporting Documents
a. Employment Letter
b. Medical Examination
c. Form I-94, Current visas, passport
d. photographs
e. Birth Certificate
f. Marriage Certificate (if applicable)

刚好缺了博士成绩单和verification of work experience。当时没人指点我，走了不少弯路，希望朋友们从我的case得到一点启发：即便请律师也要自己过问自己的事情，一定要自己把关。
