British consulate in Oakland
Oakland is not one of the nine places where the UK keeps a consular office in the United States. The office that covers it is the British Consulate General in San Francisco, 10 miles away by road, about 18 min at the speed limit.
Which British consulate covers Oakland?
The FCDO says Los Angeles covers southern California and San Francisco covers the north, but it names no counties. Our reading puts Oakland (Alameda County) with the British Consulate General in San Francisco.
None of the British offices in the U.S. issues passports or visas. What the British Consulate General in San Francisco does in person is the emergency travel document and a limited notarial service, both by appointment.
