I'm trying to get residency certificate for buying motorbike and for motorbike license.
So when I go to the immigration in chiang mai, do I need to double my document?(example: copy of passport, house registration of the owner)
As you can only get one thing for one residency certificate
TLDR : Answer Summary
When applying for a residency certificate in Chiang Mai for the purpose of buying a motorbike and obtaining a motorbike license, you will generally need to obtain multiple copies of the certificate. Based on community advice, it is recommended to obtain one residency certificate for each purpose—one for the motorbike registration and another for the motorbike license. It's suggested to prepare copies of all required documents such as your passport, visa, TM30, and photos. Make sure to verify the specific requirements at the immigration office, as some individuals reported needing different residency certificates for each application to avoid confusion.
