How long to be a resident to get an uncontested divorce?

My wife and I separated and I moved from where we lived in Seattle to Los Angeles. I’ve been here 2 months now and I want to finalize a divorce. My wife and I are on good terms and we already divided our property and other assets. How long do I have to live in California before I can file for uncontested divorce here? I’m from Iran and have dual citizenship in Iran and the U.S., does that affect the divorce in any way? Do I need a lawyer to file? If I do, I would prefer to work with an Iranian lawyer.
