To Pijiang: thanks and more questions.

Thanks, Pijiang. The problem is to find an employer free from H1B quotas. All F1 students know the hurdle now and they all prefer cap-free employers. With the economic recession, more and more employers are unwilling to do sponsorship at all.
I need to get prepared. If my application for H1B fails next year, what may I do?
Up to now, I have 2 presentation at national conferences. I will try to publish and present as much as I can in the following year. To get O1 visa, how many publications and presentations do we need?
Apart from O1 visa, what else can you recommend?
Thanks.
