Can I hold a yellow book under my wife's Blue Book and have a TM 30 at a different address?

Yes, you can have your Yellow Book registered under your wife's Blue Book while also having a TM 30 under your condo address. The Yellow Book is relevant for residence permits and other identification purposes, while the TM 30 signifies where you are residing currently. Although these documents are managed by different authorities (the Amphur office and immigration), they may request to see the Yellow Book when you apply for a residence certificate at immigration. However, some users have reported being able to use their lease agreement instead of the Yellow Book for certain processes.
