I needed VE so I could get a B. Singapore would not process application for B while on a live O. In the end I had to pay a facilitation fee for the Immigration Office to cancel the O. Had 7 days to leave country. Did border run to Cambodia and came back on VE. Flew to Singapore got a 90 day B. Came back to Thailand had had B extended to 2 years with a WP. I got 2 free expense paid trips to Singapore out of it though :-)
You might wish to contact an agent with "Contacts" in Immigration. They can check to see if there is any note on your record as if Ankara have done this it could effect applications elsewhere.
First one must be in person or by post. 2nd one can be online but if you leave country and come back it resets ie the first report has to be in person again
You are meant to stay in the country you applied while you visa is being processed. If they look through your passport at interview and see Thai stamps you are in danger of visa rejection.
It is not meant to happen but many have done it. Not seen anyone post they have been penalised if they have done it. There was a post that loked like someone had been caught out though during application. Embassy where they applied asked for proof they were in country when they had returned to Thailand
