What steps should I take to obtain a death certificate for my aunt in Thailand?

To obtain a death certificate for a U.S. citizen who passed away in Thailand, you need to contact the U.S. Embassy in Bangkok. They provide a "Consular Report of Death" which is essential for legal procedures. It is important to gather information from the U.S. Embassy website for detailed instructions. It is not necessary to visit the immigration office or police station directly for this process.
