I'm puzzled by the Receipt of OPT Application. It didn't mention the processing time, only said it depends on case. At the bottom of this receipt, it says some information about I-130 (Petition for Alien Relatives). The fact is I never file any I-130 application.
I'm very scared about this situation and I desparately need your help. What should I do? Are your OPT receipt (recent cases) the same as mine?
Thank you so much.
