Can I enter Thailand on a Visa Exempt or Tourist Visa and later change to a Non-Immigrant B Visa without a certified university transcript?

Hello.

I was wondering if anyone has experience entering Thailand Visa Exempt or on a Tourist Visa and then changing to a Non-Immigrant B Visa at the Thai Immigration Bureau?

As I will eventually be working as a teacher in Thailand, my specific question relates to the requirement of a certified university transcript. The process for certifying a university transcript in the United States is extremely time consuming. I’ve already initiated the certification process in the United States, but I may not receive my certified documents in time. I was wondering if anyone knows if it is possible to certify a university transcript in Thailand and how to do it?

Thanks,

Brian
