hello!

Just thinking , if someone own 2 pass board , and have 2 different valid Thai stamps inside for e,g a tourist visa, and a non imigrant, both are valid, is it then possible to stay , with each pass board 3 month , in total

6 month?

I talk this year with a German tourist have to passboard when he go often to china Taiwan and he also use 2 stamps valid from consulate?

But I think its not possible stay 6 month in total withouth leaving?

He can have 2 passport with 2 different visa, but he can be only with one legally in Thailand.

To switch/extend he has to leave and fly back in.

Flames removed. Entry into Thailand will be 90 days or less and visa is only used for entry - not for stay - so a new entry would be required to obtain a new stay and when departing previous entry would end.

If the visas are procured at the same time the addl 2 visas will be worthless save for addl trips outside the country. The visas will expire on the same day. No win, only complications and now you have a worthless visa (2) in your "pass board" which only counts against you wen yo make a visa again.
