Hi I’m on non o Thai wife and is due in May. Last year we went for extension with our daughter.(born in thailand)

Here’s the question. Do we need to bring our daughter( 1year+ and doesn’t wear mask and active like a monkey) along for the extension or just me n my wife will do?

And what is the document that my wife need to retrieve from another government department to show to immigration that we are married.

Thank you

My current marriage visa extension permits me to stay in Thailand until June 6, 2019. I want to extend this visa for another year. When do I have to go immigration to apply for another extension? Can I go on June 6?
