I applied for my LTR while I was still in Thailand and selected Bangkok as the pickup location. However, due to the lengthy processing time, I had to leave Thailand in the meantime. If my application is approved, can I re-enter Thailand on a visa exemption and then switch to the LTR visa, or will I need to obtain the LTR visa from the local embassy first? The embassy is about a five-hour drive away, and I would prefer to avoid that trip if possible.
