ahh.... just go to an agent.. try TVC here in this group. They have good and real reviews. Save your money. The TEV is fine but if you cannot pay there and then ... you are right.... they don't give a dam.
okay.... thank you very much for the correction and education. The US doesn't "cut" the old passport. Find it strange that the UK does as they didn't cut mine.
2 weeks is a bit much and not the regulation at all! Figure the officer was having a bad day or some such. However, you really should stay a few days away on your 'bounce'. Thai immigration likes to see that. Lessens the flags that can appear if you have a number of 'bounces'. Makes you look like a real tourist and as Thailand now wants to be and it already sort been seen as a hub for SEA... it gives you the appearance of simply traveling. But get a proper visa if you plan to stay long term. An agent can help depending upon your requirements, age, etc.
If the poster is transferring a Non O (retirement/ marriage/Thai child/etc) or a O/A based upon whatever or a B visa you certainly can transfer the stamp from the old passport to the new. If renewed via a consulate/embassy the new passport will come with a letter asking that the Thai visa stamp be transferred (that is IF provided as some do and some don't). However, It has been known that if one carries both the old and the new and show them at immigration/passport control it seems to also work. Keeping photocopies on your phone of both passports is essential if you go that route. Some here have stated that the latter makes sense and I do know those who do it and travel all the time without issues (air and land). However as with most things in the Kingdom... "sense"???.
