You might want to visit, the weather has been unseasonably warm. Tell immigration that you are a tourist on vacation. Don't mention working or trying to find work.
There are hostels in SF where you can stay for cheap. Most are in the Tenderloin/Financial area. I've never seen the inside of those. I have actually stayed at one hostel, to check it out for a traveler friend. Element Hostel. It is in the same building as Medjool, quite possibly the stupidest nightclub in the city. It's a good hostel, though, and I think the only one located outside of downtown. http://www.yelp.com/biz/elements-hotel-san-francisco
The mission is a bit grimy but at least its where the young do their thing.
Also I'd actually just do a vacation, the Bay Area is a nice vacation spot. Tons of stuff to do and see.
Heading to SF for a short period seems like a good idea.
Since you don't seem to have a network there, it is probably a good idea to do a recon trip. This also works well with the visa situation.
It is probably considerably easier to meet people willing to sponsor you if you meet them in person, so just take a "vacation" to SF and plant your seeds.
This also gives you the chance to see if you really like SF, although i would be surprised if you didn't like it.
Good luck!
