wrong!!
from personal experience! took less than a week from when i sent them my PP to getting it back
did mine online, ( 2x) no problem. re entry permit issued at same time
ONLY hassle i had, I needed to renew my Thai license so had to file a new tm 30 at phuket immigration ( as to get the extension, they have you living up country at an easier immigration office ) to get my COR>
NO problem
