The person goes with the new passport and the letter of replacement from the Embassy to the Immigration in Bangkok and ask if a new Admitted until stamp can be placed in the passport.
There is no such thing as a 2 months tourist visa stamp.
Or on the other hand, IF you are on an entry non B visa for 90 days, you cannot apply for a retirement extension directly, You have to leave Thailand and apply at a Thai Embassy/Consulate for the Non Immirgant O visa based on being over 50 years of age, get 90 days on entry and apply after 45 days for the 1 year Extension of Stay, but be aware the 800.000 Thb needs to be at least 2 months prior application date in a bank account on your name.
No need to worry, if you leave without a re-entry permit the Extension of Stay is void and you need a new visa to enter Thailand if you do not want to go visa exempt.
I guess things got mixed up with translations, as you can not change an Extension of Stay based on marriage into a new type of visa.
And that is the reason that he told you to apply at a Thai Consulate and the Extension of Stay ends if there is no re-entry permit at leaving the country.
yep, and if that is the case than it becomes a totally different story. We just have to wait and see if she is willing to share that important information.
