- Address of your first stay in Thailand.
- Health Declaration: Details of countries visited in the last 14 days and any current symptoms.

The TDAC is free; avoid third-party sites that charge a fee.

TM30 – Notification of Residence

What it is: This form notifies Immigration where you are staying. It is a legal requirement used to track the location of foreigners for security purposes.
Who files it: Technically the landlord or hotel provider. However, you are responsible for ensuring it is done and keeping the receipt.
Tips: A new TM30 must be filed every time you re-enter Thailand from abroad, even if you are returning to the same house. Most immigration offices now require a copy of the TM30 receipt before they will process any other paperwork (like visa extensions).

Tm30 Example

TM47 – 90-Day Report Form

What it is: Confirms your current address if you stay in Thailand for more than 90 consecutive days.
Who needs it: Long-term visa holders (Retirement, Marriage, Business, etc.) who have not left the country in the last 90 days.
Documents needed:
- Passport (original and copies of the visa and entry stamps).
- Your TM30 receipt.
- Completed TM47 form.
Tips: You can file this 15 days before or up to 7 days after your due date. If you leave Thailand, your 90-day clock resets to zero the day you return.

TM8 – Re-Entry Permit Form

What it is: This "protects" your current visa. If you leave Thailand without a TM8, your long-term visa or extension is automatically cancelled
Who needs it: Anyone on a long-term extension who plans to travel abroad and return.
Fees: 1,000 THB for Single Entry; 3,800 THB for Multiple Entry.
Documents Needed:
