Lost my job on h1b

I lost my job on h1b and its been around 35 days. I want to know if there are some legal ways I can still stay in US even after my 60 days are expired. One of my friend told me about transferring to B1/B2 visa so I wanted to know of it is safe to switch to this visa category and what are the steps in doing that? How many days does it take to switch to B1/B2? Should I do it now?
