How long does it take to renew a US passport at the embassy in Bangkok?

Renewing a US passport in Bangkok can take varying amounts of time depending on the method chosen. Generally, the US embassy website suggests a processing time of 6-8 weeks for a new passport. However, users have reported quicker experiences, with some receiving their renewed passports via the post office's EMS service within 3 weeks. Others mentioned that online applications without an in-person visit are now accepted, which also led to receiving passports in under 3 weeks. Additionally, users raised questions about how passport renewal affects visa stamps, with suggestions that the old passport may need to be kept as the stamp might be transferred.
