Seems also “simple” and “clear” that PR isn’t mentioned on the priority or Thai national lanes, yet PR holders can use those lanes.
Likewise, the term “Country of Residence”also seems “simple” and “clear”, yet I can’t select Thailand.
If what they write really was so “simple” and “clear”, a PR holder would have to fill it in because he’s not a Thai national, but he can’t fill it in because his country of residence is Thailand.
I guess I’ll just go to the lanes for Thai nationals without this form and see what happens.
