Also for example at Chiang Mai immigration do I have to join the big queue or is there a smaller queue dedicated to re-entry permits and visa transfers?
I mistakenly bought a coffee grinder mail order and I realised it was 110v before I plugged it in. So now I have to use a transformer. Also things bought in Japan like stereo equipment is 100v so I to use a transformer for electrical from Japan.
This depends on the Immigration officers. I have had them complain about not staying together and the other way we stayed together and they complained that we should have stayed in our correct channels.
