dual national issues - my baby came into thailand on her us passport (30 day stamp) as we are still waiting on her thai birth certificate. once we have her thai passport, will we have to do a visa run? or is there some way we can change her over in thailand. seems nuts for a four month old to have to border hop! had any dealt with this before?

a friend has suggested that immigration are pretty lax about babies overstaying and we can just wait until we actually need to leave the country to make the switch.
