90 day reporting is not related to any other Immigration matter. So your 90 day report remains the same. 90 day report only stops and restart at day 1 as you leave and reenter the country.
yes I did call the Embassy of Thailand in The Hague or this is allowed. As my "old" passport did have around 11 months validity left. Now I not need to renew my passport for 10 years. It made my life a little easier in Thailand.
Benjamin that is a different situation. BUT it can, in The Netherlands anyhow, be also. I traveled from Amsterdam to Thailand with my multi Non-O visa still valid in my old passport.only the personal data page made invalled. So my Visa still valid. As long NOT punch the valid visapage. Other whise the visa will be invaled. But using the new passport to travel into Thailand. And getting my 90 allowed days stamped in my new passport. So ussing 2 passports. But that is another still as what I mean with 2 passports. These 2 passports will, most likely, have the same validity dates.
yes same country indeed. Basicly every business man, or lady 😊, can issue a second passport. Exactly for this kind of issues you need to travel abroad already but next week you need a visa for another country. So then one passport stays at a embassy. And on the other passport you travel in the mean time. Also a second passport can be important when travel to conflicting country's. 😉
This is not solving your problem. But as a sailor you can apply for a second passport. But then you cold try to let the passport, with the visa, sent per fast track courier to a few ports ahead to the office of the ships agent in that port.
I understand you can also proof your income by 12, Thai bank as i understand, bank-statements proving that you sent into Thailand minimal the THB 40.000 of the THB 65.000 per month. Depending on your type of extension one is using. Abroad income bank-statements will not be accepted as i presume.
