Can I get a residency certificate with a DTV visa to register my bike in Thailand?

Yes, you can obtain a residency certificate with a DTV visa. To apply, you will typically need to provide a photo, copies of relevant passport pages, visa, entry stamp, and a TM30 form. Note that different immigration offices may have slightly varying requirements; for instance, Bangkok might require your first 90-day report to be completed, while Jomtien may allow you to proceed with just the TM30 submission. Processing times can also vary between locations, and using an agent may help speed up the application.
