Weather delays about as likely in California as Florida so remove that as a decision factor. Both states have a wide variety of great (and not so great) schools. As already suggested do take a look at Arizona as well.
On a logistical level Hong Kong to LAX or SFO is a single hop. So you'll save time and money right there. If you choose California plan it close to San Francisco/San Jose, Los Angeles or San Diego so as to experience complex airspace.
I can't speak to specific school recommendations but my suggestion is to figure out a location and then use the AOPA website to screen Flight Schools that can help you navigate the Visa stuff.
Good luck in your endeavors!
