Hello everyone,

I'm confused about flying from Bangkok to Kuching:

- does Sarawak require some special document/visa?

- is stay limited to 30 days?

- something else?

Thank you very much.

It's been some years but I have been to Sarawak several times and did not need any special paperwork or visa for entry.  You do need your passport even if arriving from West Malaysia and will be stamped in and out.  As far as I recall the entry period was the same as the West side, 90 days in my case.
