Hello everyone, this is my first time in Thailand, hope you guys can give me some ideas on my covid extension :

I have visa exemption for 30 days. I landed on 18 March and tried to apply for covid extension in Jomtien on 21 March, got told to come back on 25 March (I read it somewhere that it's the deadline for covid extension).

Can I switch to another immigration office in another city to further my application ? Or must I stick with Jomtien once I started it there ? So far no stamps given, no forms collected whatsoever.

I wanna travel around Thailand in the next few days already, dun wanna stay in pattaya for three more days just for this application if I can redo it somewhere else.

Any advice will be appreciated, thank you all for help !
