Do you have legal custody in Thailand and India? If so then you would want those documents in case any issues arise - also a consent letter from the mother - since you have asked this question many times, you might want to consult a lawyer if the mother did not consent custody and the child was removed from Thailand without a court order, your sons mother would need to go to a notary and give consent with her information and sons information
Depends you will sweat it out until your office reviews - Thais love paperwork and reviewing it and following each and every step, very little in the way of exceptions is my experience
she crosses she gets put in a cage for about 90 days, then taken advantage of as a undocumented person under the table subject to immigration raids and deportation….tell her to try it out, I am always amazed by the amount of racists that go live overseas in foreign countries though lol 🤦🏼♂️
she can she just needs a visa first and there is a application process for that which she didn’t pass, most pass and get visas it’s not rocket science and embassies around the world issue visas everyday….you are the one saying people cross the border illegally everyday? would you cross the border illegally into Thailand?
that’s odd then - maybe the embassy just doesn’t like Thai ppl? I always see Thai people on the plane to Los Angeles though about 30-40% so more people approved than denied is my guess
