Non B fingerprints & slash numbers in Thai visas, residency and work permits Posted July 19, 2018 Thanks Joe, this is my 5th education-related year Non-B and the first time I've heard of fingerprints being required. In the last 4-5 years I have only provided one Thai police check - at the beginning of my first year, and fingerprints were never asked for. I guess the local MoI office/police station interpreted and processed it their own way! This situation has only arisen because the MoI recently advised me to apply for a different type of Non-B - one with a slash number /nnnn, which they say will give me the right to have my name on land chanotes as a co-owner up to 50%. I'd never heard of this before either, but greatly appreciated if you've got any info on this, cheers.
