For those who have been using MTT here was my experience @ CW today....
Arrived @ 7:30 am to close the loop on my latest 60 day extension. Don’t be fooled by the empty building....I was number 149 in the queue despite arriving before 8 am.
Head around to gate 2 from the entrance and you will see an information table set up...the immigration officers were really helpful and friendly.
The process is much more streamlined that MTT and you will receive a queue number that corresponds with a seat number. Find your seat, wait and then just follow the queue around to the main desk where they will give u another queue number for the appropriate counter (j) which is to the left.
Business started at 8:30 and I was out by 9.15 am.
