I got my OPT in 2000 after undergraduate. Now, I am trying to apply for OPT again after graduate school and the I-765 (application form for OPT) asks whether I have ever applied for OPT? If yes, to provide necessary documentation. I do not have my EAD card from 7 years back. What document can I provide? Or should I just say that I never applied for OPT as I have gone back to Nepal for a year in between? Or should I just write a nice letter saying that I do not have the EAD card anymore and just send the copy of my degree as a proof that I applied in 2000.
