The facts you provide are minimal. Often the Courts in Pakistan are more friendly to the husband than the wife, and I am not certain why you would want a divorce in California instead of Pakistan.
Any immigration question would be better addressed to an immigration attorney. I'd need to know more to tender a meaningful answer to any California Family Law question. Good luck.
As stated above -- I have NOT actually stated any legal opinion, because I need to know more before I can start to form one.
