Thank you, guys, for your help! Have a nice time wherever you are!

I hope it's not a problem that he's going to be overstaying for a couple of years.

And maybe you know how to fly around the county? Can we just use an empty new passport for his travels?

@James *******

he's 6 yo. He entered Thailand with a Russian passport, but he is also a Romanian citizen. When his Russian passport was close to expiring, we made a Romanian passport for him (because it was a lot faster), but then they told us in Immigration that it was a mistake and he needs a new Russian one. Now he has an expired Russian passport and 2 absolutely empty new ones 😊

@Tod ********

thanks! I thought the immigration should transfer the entry stamp in a new passport, at least that's what they told us.

So, when we will be leaving Thailand, we need to show both passports. The kid already has a year of overstay
