How do I register my marriage to my Swiss wife? I’m a US citizen and live in northern California. I run a small business and it’s almost impossible to drive 4 hours to SF during my work week. Can i register by mail?

Yes, if you call consulate they are very friendly and can email need forms and walk you through the process. You will need to fill out doucuments and have a marriage certificate and birth certificate, both need to be originals not copies and issued with in 6 months of submitting. Marriage certificate must also be verified by an apostle in the state of issue. You'll also need to send a copy of your US passport.

You can register online and by sending documents
