you jumped in with both feet saying that they would sure be orphans in your country, you didn't even ask the question, before you assumed, I have a lot of respect for people that are trying to give kids a chance in life, And yes simpleton comes to mind.
If it's the same as UK you have 3 months to enter Thailand to activate your visa,don't think it should make any difference what country you fly in from,
so all thai lady's don't have the option, I totally agree with what you saying but they have a option,big money comes to mind,like I said in a earlier post, don't tar them with the same brush
to many extensions would be fround upon, that's why I'm leaving for a few days, come back to activate my visa, it's not a big expense to keep in the good books as they say.
