I have the DTV and I am currently in Thailand with my partner. Does anyone know if it is possible to add my spouse (she is from the Philippines) onto my DTV whilst we are both in Thailand. Or does she need to leave Thailand and then I apply on her behalf. I have received mixed responses on this so I'm not sure what the correct process is. Any pointers would be greatly appreciated. Best wishes.
TLDR : Answer Summary
To add your spouse from the Philippines to your DTV, she must leave Thailand and apply for her own DTV dependent visa from outside the country. You will need to provide a copy of your DTV, your marriage certificate, and proof of sufficient funds (500,000 THB) in a bank account.
