It can be changed in thailand but need more then 15 days or more on the actual.....but go just and ask...but not tell that she go to school...just if its possible to change here...
Normaly the approval in Penang or KL needs from the morning u bring all your papers from the companies and the receipt from the office of labor with your passport and they check it till the next day after 2 pm so .....where is the problem....did u left KL without ?....yes is its proved just go and get the stamp ....but I think it needs a night to stay in KL or in Penang. But if u go to Penang use Jimys Places agency....they fix it for a small amount
