I’ve done the online 90 day notification twice at CW. The first took 10 days to get approved, the second (with all of the same information as the first) took 20 days and was rejected yesterday without any explanation. I’m leaving CW now after having to pay 2,000 baht for being 4 days late submitting my 90 day notification. Absolutely no one at CW cared that I had submitted everything online 3 weeks ago or would/could tell me why the online application was rejected. Very frustrating.
