Hi, we are in the process of doing it as a family of 4. You need to do the main visa first and then when you receive that visa, you can apply for the other visas. For the dependent, they ask you to upload proof of relationship (birth or marriage certificate) and the main visa, as well as financial sponsorship and bank statements, and proof of location (hotel booking, entry stamp of the country...)

Hello, we are going to Cambodia this week to do the dtv. I just have a question, for the place of issue, did you put exactly what it says in your passport or something else?
