I stay in Chiang Kham, Phayao, I got my first 3 month non-o retirement visa at the Chiangmai immigration office. Since my residence falls under the service area of the Chiang Khong immigration check point I would prefer to get my one year extension of stay (based on retirement) from there. Would appreciate some guidance.

The website of the Immigration Bureau gives this address for the Chiang Rai immigration office:
117 Amphoe Mae Sai
Changwat Chiang Rai
57130

No. Only at Mae Sai Immigration Office. This Office relocates to Central Plaza in Chiang Rai city on the first Saturday of each month.

Thanks for your advice
