Since i'm not a student here, i cannot tell professor to make a letter for me.
I asked DSO and he simply did refuse saying he cannot help me about TPS.
I have valid i-94 and have not been out of status.
So, my question is "Is it necessary to send USCIS a letter stating i have been staying here since the TPS given period?

Passport photocopy and i-94 form matra pathaye hudaina ra? If not, what's the best way to deal with it?
Is here anyone F2 dependent who applied for TPS and EAD? Please suggest me!
Thanks in advance.
