I just renewed my passport at the Australian Embassy in Bangkok. I have a Retirement Visa and multi entry stamp in the old passport, which I still have on hand. I plan to present both old and new passport to the immigration officer to get stamped out of the country. Question is whether the existing, valid Retirement Visa and multiple entry stamp will be transferred to the new passport on the day of departure by Immigration? I have a sinking feeling in my stomach that I will need to visit Chaengwattana to sort it out, prior to flying. Incidentally, I will exit via Suvarnabhumi before having to renew my current 90 Day Report, so that doesn't present any issues. Much appreciated to those who can offer their solid experience here. Cheers
