Can I Extend My Visa Waiver at BluPort Immigration Office or Do I Need to Go to Bangkok?

You can extend your normal 30-day visa waiver at the BluPort immigration office in Hua Hin. Local immigration offices, including BluPort, are equipped to handle these extensions, so you don't need to travel to Bangkok. It's noted that BluPort can be a convenient option with manageable crowds, but make sure to check the updated opening hours.
