I got my TN Visa, thank you! Now is there anywhere I could go in Southern California to renew my TN without having to leave the country?

One TN Visa renewal option many Californians have is to drive to the San Diego – Tijuana border, park the car on the U.S. side and walk across into Mexico, turn around and apply upon re-entry. The only requirement for this border is to make an appointment ahead of time with the Special Cases officer. Make sure you arrive early and be ready to deal with line-ups.
