Are there any minor children? Does your wife live in California?
Please do not rate this answer yet. I am simply trying to get a few details.
you can file for divorce in the Superior Court in the District where you live or where your wife lives. The Court system provides a good reference site at: http://www.courts.ca.gov/8411.htm It does not matter that you are a foreigner. Please let me know what additional questions you may have.
Okay. You can consult with a private investigator who can perform what is referred to as a "skip trace." The skip trace is designed to find the present residence address for someone. You will need to provide the private investigator with all the information you can about your wife, including social security number, driver license number, relatives, age, date of birth and employment.
Once you locate your wife, then you can file suit in the proper court and allege the necessary residency requirements.
Please let me know if you have additional questions.
