Hi, I want to do an in-country visa conversion from a tourist visa (entry on exemption of visa actually) to a non-immigrant 0 for my 5 month old son. He would be a dependent on my non-immigrant B visa. Yes, we have more than 15 days left on the visa. Two questions:
1. Is this only possible in Chaengwattana? I am under BOI and usually go to Chamchuri square for my visa/WP.
2. What documents are required? In a group search I only found the requirements for retirees. Thank you
