What are the bureaucratic requirements for expats arriving in Thailand, including TDAC, TM30, and TM47 forms?

Before flying to Thailand, ensure you complete the TDAC online within three days of your arrival. When renting a condo, obtain the TM30 receipt from your landlord. For your 90-day stay, you must submit the TM47 form in-person at the immigration office; this can be done within two weeks before or one week after your 90th day in Thailand. This covers the crucial bureaucratic steps an expat must take.
