I went to the 'new' immgration today to do 90 day report. Just can't avoid that Chaweng - Nathon schlep!
No problem with the 90 day report, I was in and out in ten minutes, everyone friendly and helpful. I got there at 9.45 and only eight customers in office.
I did clarify two things though.
1. The medical report must be from Samui Hospital in Nathon.
2. They now require a copy of the "Blue Book" for my place of residence in addition to the rental agreement and copy of landlord's ID that was previously required (on the list of reuirements it says "household" but the guy at the information desk showed me what this meant).
Regarding the medical report, there was a previous post that said the poster had got a medical for certificate from Thai International Hospital. I have not seen a follow up post saying that this was accepted by immigration or not.
It would be helpful if people who post here about this subject would advise other users what the result of their actions were.
