There is a resort called Sierra Summit about 65 miles northeast of Fresno California. It's a very nice resort with 1500 feet of verticle and 600 acres, but it is a victim of it's geography
If you live in the San Francisco area or north it's just as easy to go to Tahoe, and if you live in LA or south, it's almost as easy to drive to Mammoth. And Big Bear also hems them in to the north. As a result most of the skiers who go there are from a fifty mile radius of Fresno to the north and west, and maybe a hundred miles to the south.
When I learned to ski there in 1995, most of the instructors were Austrailians. I haven't kept up with the situation there. They could be getting instructors from somewhere else now, or They may already have processed the visas, but it's something you could check on.
they have a web site, http://www.sierrasummit.com
