Hello!
I spent 4 months in Thailand (visa exempt 30+30 extension x2), then had to go back to Europe. While in Europe, I applied for Multi Entry Tourist Visa. I had my flight to Thailand already booked, as stated in my visa application. The processing ended 1 day after I arrived in Thailand. So, I entered with another visa exempt, although I have a Tourist Visa fully approved now.
Should I go to immigration office to inform them I have a Tourist Visa to change status? Or should I just stay in Thailand with visa exempt, then fly out and re-enter enter using my new tourist visa?
Thank you for suggestions.

Comments indicate that one cannot activate the unused visa while in Thailand and should leave and re-enter the country to validate the METV.
