My 485 was RFE 了. 唉！
In the letter I need to proof my nonimmigrant status from year xxxx to xxxx. I was a F2, H4 during that period. However, I had two I-20s. One had my name on the last page (used for spouse to enter United states) with correct date and another i-20 with my name on the front but with the wrong date (shorter than my hu*****and real F1 status and did not connect well with my hu*****and OPT starting time).
请问大虾们：1. 给那一个对路。
2. 劳工OPT那功夫，how to establish my non-immigrant status.
多谢！
