Currently I'm holding Thai PR ( Blue book). I have applied my re-entry permit at the Thai immigration
Completed Part 1 &2
1) Immigration stamp my residency blue book (1 year)
2) Immigration stamp my passport (1 year multiple)
Would like to find out the following , when I depart at the airport, am I expecting the immigration officer to stamp the following
1) My passport ?
2) Residency Book ?
TLDR : Answer Summary
When departing Thailand with a re-entry permit and a Thai permanent residency (represented by the blue book), only the passport will be stamped by the immigration officer. The residency book is considered irrelevant for departure processes.
