Is it better to apply for a reentry permit at the local immigration office or at the airport in Thailand?

When deciding between applying for a reentry permit at the local immigration office in Chiang Mai or at the airport, it's generally advised to opt for the local immigration office ahead of time. Many community members recommend this approach for added peace of mind, as it allows for a more relaxed preparation before traveling. While getting a permit at the airport may be quicker and less hassle, especially if you're familiar with the process, applying in advance can help avoid potential delays that might occur during transit, particularly in Bangkok. Making an appointment at the immigration office can expedite the process significantly.
