Can I extend my 60-day visa exemption in Thailand for an additional 30 days without booking a hotel or return flight?

You need to apply pattaya immigration if residing in pattaya

Get extension first

as long as you arrived in Thailand and not using an entry agent, you can do one 30 day extension per year.

you can do it long before your stamp runs out, and they'll give you 30 days PLUS the days you had left

you can download the tm7 form as a pdf: print and complete it before you go, so you can look up things like the full address of where you are staying

you will need a tm30 which your accommodation must provide to you; if they don't know how to do it, go to immigration and have an officer speak to them on your phone in order to ask them to come down and process it

i just extended my extra 30 day stay at Suratthani Immigration, just needed to show where I am staying , no proof of return ticket

Fill in a form at immigration

TM8

Bring passport

Receipt from your current

Accommodation

Possibly 1 x 4 x 6 photo

1900 baht cash

Why make it difficult? Apply in Pattaya.

No need of a return flight.

All you should need is the TM30 receipt from the hotel you are currently staying in, there should be no need to book another month etc
