I applied for CoR at CW earlier this week (not arrived yet). She asked for my TM30 and my 90 day report which I gave, and then said after doing 90 day it was necessary to make an updated TM30 showing departure date to match the permitted until date on passport, as previous check out date was left blank. Anyone else had this? I pointed out that a new TM30 would not be able to show my actual arrival date in Thailand and she said it didn't matter. It baffled me but it didn't affect the CoR, I was told it was something I could do later.
The other thing I wasn't expecting, I was told the CoR is only valid for one month - wasn't it previously a year?
