Praise Report.
Chiang Rai Immigration Office Today wasn't that busy at 11.30.
Picked up TM7 form. Had to drive down the road to photocopy as photocopying booths next to the carpark were closed.
Copied Visa page in Passport, Photo ID Page of passport, 1x Passport Photo, 1900 Bhat exactly, TM6 & TM7 forms.
Returned after their lunch break.
The officer outside helping with CONVID 19 procedures was very friendly and helpful.
I was asked next time to fill out form with a blue pen.
Took about 30-45 mins inside to process.
Grated 30 Days Tourist extension starting from the current visas expiry date on Friday.
I noticed a foreigner having challenges with their Visa processing but that looked more to do with their unorganisation of forms and attitude towards the offices.
Thanks for all your help everyone.
