@Thomas *******
Sounds like reading comprehension isn't your strong point.
My point is there are NOT MANY westerners at least, living in Thailand who face this situation because the VAST majority are married to Thais and have Thai citizen children. I don't know a single farang who has foreign children living here, though I understand they exist, but to me they are basically long-term tourists.
HOWEVER, it is reckless for any organization to suggest that deliberately allowing your FOREIGN children to overstay will not have future repurcussions.
Already some DTV applicants are finding their applications refused for previous overstays (although these are probably documented in their passports as the MOFA does not yet appear to have access to a more wide ranging database).
In Phuket, foreigners who've overstayed by mere HOURS have been arrested at the AIRPORT!! So to say that children won't have future problems such as possible visa denials once they turn 18 or 20 (probably 20, since that's the age children become adults in Thailand) is ridiculous.
The last part of my comment pointed out that the largest contingent of FOREIGNERS who are NOT married to Thais and live in Thailand with their FOREIGN spouses/children, that being migrant workers, also have the highest chance of their children being Thai citizens, hence their children do NOT face this issue.
