回複：File i-539 statement sample

Hello,

Does anybody have a sample statement letter for filing I-539 (change status from H1b to F1)?  Can I just say I lost my job and want to go back to continue school? 

-That reason is horrible. You need to address why you want to study after working such as want to update your knowledge, etc. whatever reasonable.

If you have any do's and don'ts suggestions, I will really appreciate it. Thanks!
