Thank you for your response. I am attending a college in U.S. on F-1, and I can legally authorized to work during the semester or vacation using CPT or OPT. I am considering flying to Silicon Valley this winter, but I am not sure if this is worth the cost. I don't think I can meet many people there if I do not have a network.

I have been waiting for almost 2 weeks, but I am not getting any email or phone call. This is exhausting and dismal...
