Please advise current visa exemption and 30 day extension requirements

Hello! I’m from Poland and I’m flying to Chiang Mai at the beginning of October on 30 day tourist visa. I’d like to extend it further as soon as possible. My questions are:

1. Can I apply for the extension as soon as I arrive to Thailand?

2. How do I acquire the maximum extension which is 45 days?

3. Do I need to have an onward ticket upon entry to Thailand?

I’m sorry if this has been asked but I’m struggling with the Facebook posts search. Thank you!

Can I apply for 30, 60,or 90day visa in Thailand when I arrive on my 30day tourist visit?

UPDATE Notes from the field - 30 Day extension

Success! -- (USA/Bangkok Office/30 Day Tourist Visa)

Two weeks ago I posted about my experiences getting the "Under Consideration" stamp. And yesterday was the day to go back to receive the final approval.

Unfortunately I did not make an appointment and was told very politely and nicely to "come back tomorrow" even though there was hardly anyone there.

I was assured that coming one day late would not affect my decision by more than one staffer, so I reluctantly ate the 700 baht and "came back today" spending another 700.

Please make the appointment before going!

Anyway, I got there today and in about 15 minutes was just handed back my passport and told to have a nice day, in the Thai way of just efficiently taking care of things without bothering to explain too much. (Sometimes that is hard to get used to).

So I am good until October 26 again. Which gives some time to complete long term plans. Let's hope the new 90 day visa will apply to people in our class.

Good luck to the rest of those going through the process!

From what I saw the process was more or less perfunctory and it seemed that everyone I saw there seemed to be happy with their result.

So long as papers are in order they do not *seem* to be denying anyone at this point.

Hey friends, looking for some Visa advice. I'm in Surat Thani right now and I'm wondering if it's possible to do a visa run over land to Ranong for a 30 day tourist visa? Do you need an E-visa to just get *into* Ranong? I'm an American passport holder. Thank you in advance!!
