I'm coming to Cali baby!

So I've lived basically in one town in South Africa my whole life.
In a few days I meet with the Visa people and should be in Cali by end of august!
Half the reason i'm coming to cali is to start Jiu Jitsu properly (not at alberton wrestling club, which is not what you would think! Awesome guys but very closed minded)
So I was wondering what you guys think about a few things
1) If I'm a fresh beginner in JJ, which 10th Planet would be best for me to go to?
2) How easy is it to get a medical marijuana certificate and do you have to be a citizen for it?
3) Where's a good place to start looking for a place to stay, doesn't have to be a nice area or anything just relatively safe.

I'm trying to get as much sorted to destress the whole process as much as possible so any help or advise would be much appreciated guys.

Thanks and much love for 10th planet

time to move

This died quick.
