I came into US with no credit too, and had absolutely no problem to rent. Actually, I had much more problem finding lenders willing to accept my pets than my credit (for some reason, most of the local apartments hate pets, no matter how small and harmless). Yes, they asked for security deposits (not exorbitant - 1-2 months, and many require it even with good credit), and yes, car loan I got was outrageously expensive compared to what I could've gotten with good credit - but I still could buy anything I needed.

I guess maybe in the Silicon Valley everybody is used to immigrants so nobody is surprised when the person with no credit shows up, especially if they have the actual money. If you have no money that's different, but then the primary problem is not credit.
