It's ridiculous really that they have to report that if they (the Africans) are in large enough numbers to create problems in BBK somewhere, and news reports etc to this effect, it obviously means they aren't working/being legally here etc and are a self-made issue. Regardless of the origin of any none-Thai people here, especially if they are in large enough numbers, it's the fault/problem of immigration or the airports/embassies for granting them visas in the first place, even if on arrival....that african's were being pushed out of bkk soi 2-4 by police and were swarming into hua hin.
It's the Thais own fault that these problems exist because their own officials are not enforcing their own laws and regulations until it's too late.
Has the list grown of 'visa on arrival' these days to include every arse-end country on earth or are they holding passports from countries that they are not the origin of? Which, ironically, as an aside, wouldn't surprise me as this has reached endemic and ridiculous proportions.
As for the locals making up their own minds about whether certain nationalities are no good or not welcome......well, up to them......their country and experiences of such individuals or groups of such.
Fair enough, unless someone is going to go all "Cherie Blair" on me.
For me, I'm fairly ambivalent these days as it's gone way beyond the point of reversal almost everywhere.....so whatever really.
