What is the processing time for the 12-month retirement visa extension in Thailand?

Pattaya always makes you return the following day after 2pm. It's to demonstrate their power over those who pay their wages; to screw another 40baht parking fee out of you; to add to the poor air quality. After an IO has scrutinised your docs, there should be no reason why he can't do the stamp there and then, even when you've done it all 20 times already like I have.

Under consideration is when applying for it - when you do your 1 year extension its the same day

I've always had 'under consideration in Phuket. Non-O/kids

I get mine on the same day. I use a provincial Immigration and they are very effective. The 1-year extension, a 90-days report and a single re-entry permit, everything done and dusted on the same day within 25 minutes. I never had to wait, I was always asked to sit down across the officer after I entered. Been doing it since 17 years. That's the advantage using a countryside Immigration. When we lived on Jomtien Beach for 2.5 years, I never registered TM30 there in order to avoid Jomtien Immigration, I remained registered upcountry as the application fell into New Year and I love to spend it with the family

Same day in my experience

I applied for my one-year non-O retirement extension and a Multiple Re-entry permit at 9:15 AM. I left at 10:15 AM. It cost me 1900 and 3800 baht, respectively. Then I requested a special proof of residence, required for applying for my Thai driver's license and obtaining the white license plate for my car. This was produced immediately in duplicate for 800 baht. Immigration office in Pathum Thani. Friendly staff and very quick service.

How much you pay 💰for extension because I need too go 2

I have retirement visa but not want go home

Normally, it will be issued the same day you apply for it.

Obviously every immigration office is different, so it's not a guarantee. You might get an under consideration if they want to do a home visit (rare for retirement but becoming more common).
