Can my son be on the same DTV visa as my husband, or do we need to apply separately?

In addition, you would need to pay the application fee for both you and your, supply evidence that you are related to the main DTV holder (marriage certificate and son’s birth certificate), and have to wait in Vietnam until visas are issued. The embassy will be closed from the 14th to 23rd, so you might not get results until after that

I believe you are referring to applying for your son as a dependent on your husband's DTV visa.

To clarify, your husband would first need to have his DTV visa approved. After that, you can apply for your son separately as a dependent. Please note that you will need to show the minimum financial requirement for each person (e.g., THB 500,000 x 2 = THB 1,000,000) for a period of 3 months.

If you are applying for both yourself and your son, the same process applies, and the additional financial requirement would total THB 1,500,000.
