If you’re referring to Option 2 (Dependent DTV) A child does not automatically follow the parent’s DTV, so a separate application is required.
You don’t need to return to your home country, you can go to any nearby country and apply outside Thailand via the Thai e-Visa system. This is simply because DTV is a work-based visa, so dependents must be linked by documentation.
Basic documents are usually the child’s passport, birth certificate, and parents’ DTVs (exact requirements depend on the embassy).
Again, this option is your choice, not a requirement.
It really depends on what you’re most comfortable with.
✔️ Option 1 (what many parents choose):
You do not need to apply a separate visa for your newborn at this stage. Once his passport is issued and you travel out and re-enter Thailand together, your baby can enter with you as parents and will receive entry permission based on his passport nationality (for Swiss passport, this is usually visa-exempt entry, currently up to 60 days).
Your baby can stay on that entry stamp. If it later exceeds the permitted period, children under 15 years old are covered by amnesty, meaning no overstay fine and no penalty, and there is no issue when exiting or re-entering Thailand with you.
✔️ Option 2 (also perfectly fine):
If you prefer everything to be clearly documented, you can apply a separate visa for your child, just like you did for your 4-year-old son. Some parents choose this option simply for peace of mind or long-term planning.
So it’s really about what feels right for your family both options are commonly used in practice
I’ve handled this situation in practice before, so I’d like to share real-world experience.
If your child is born in Thailand, the first step is to register the birth and obtain a Thai birth certificate from the local district office (Amphur Office).
After that, you’ll need to inform your embassy of the birth and apply for your child’s foreign passport.
Important point many parents don’t know: Your child will not have a visa yet, and that is legally acceptable.
Under Thai law, a child who is born in Thailand and has never left the country is allowed to stay without a visa, and even if it is technically considered overstay, there is no fine or penalty for children under 15 years old (amnesty applies).
Later, once you’re ready to travel or regularize the status, you can arrange the appropriate visa for the child.
Hope this helps, and wishing you a smooth delivery 🙏
Overstay on a DTV visa is usually not something to panic about, as long as you handle it correctly.
If you realise you have overstayed, you can go to the immigration checkpoint when leaving Thailand, pay the overstay fine, and your DTV visa will still remain valid. This is because DTV is a multiple-entry visa.
➡️ Once you re-enter Thailand again, your stay will reset to Day 1, and you will receive another 180 days from the date you arrive.
However — the part you really need to worry about is this:
If you get arrested or stopped by the police before reaching the immigration checkpoint (even for a small petty case), then this becomes serious. In that situation, you may not only pay the fine, but you could also face a possible blacklist under immigration rules.
So if you become aware that you’re overstaying, the safest thing is to exit the country as soon as possible and clear it properly at the border.
Hopefully, you can use a letter from your Embassy, If the new passport is issued by the embassy inside Thailand, you should have a Letter from Embassy confirming replacement of old passport with new passport
Please bring everything you have to the local Immigration Office where you registered your TM30, and ask them to transfer your visa stamp to your new passport. No government fee needed
