Hello,

You will need a photocopy of your old passport to show the ID page and entry stamp,

as the embassy keeps the old passport I expect they will give you a letter as well,

then you can go to immigration and ask for the stamp to be trasnfered.

I am not sure what will happen as you have overstayed.

You need to transfer the stamps at Immigration.

If you are on Overstay you can go Immigration only if you have a flightticket for a same day flight as Suan Plu will give you not much time to leave the country .

You can also transfer the stamps at any international airport or landborder and pay the fine .

What embassy wants the old passport? I'm American, they just punch ours - we keep them.
