TM30 in first week — your landlord must register you
May 5, 2026Sukhumvit · Experience date Mar 7, 2026
TM30 requires your accommodation provider to report your stay to immigration within 24 hours of arrival. For hotel or serviced apartment: they do this automatically. For private condo rental: confirm with your landlord they've filed the TM30 online. Without a TM30: visa extension applications and 90-day reporting are rejected. Ask your landlord via Line: 'ลงทะเบียน TM30 ให้หน่อยได้ไหมครับ?' (register TM30 for me please?). If they refuse: go to Chaeng Watthana immigration with your lease contract and file it yourself (form TM30, free).

May 4, 2026Thonglor · Experience date Feb 14, 2026
Bangkok's air quality is variable. Download IQAir or Air4Thai app on day one. February–April worst period (PM2.5 from agricultural burning in northern Thailand drifts down). Real-time AQI in Bangkok typically 50–100 (moderate), occasionally 150+ (unhealthy). When AQI exceeds 100: wear a quality mask (N95 or equivalent) outdoors. Invest in an air purifier for your apartment (Xiaomi Mi Air Purifier 3H: 4,500–6,000 THB from Lazada — arrives next day). Many Bangkok expats report that their respiratory health improves after installing a home air purifier.

Apr 14, 2026City-wide · Experience date Apr 7, 2026
Thailand's TM30 form requires your accommodation provider to report your address to Immigration within 24 hours of arrival. For hotels, they do this automatically. For rentals or staying with a friend, your landlord or host must file TM30 online or at the nearest Immigration office. If they don't, you can be fined at your next visa extension or re-entry. Confirm your landlord has filed before signing a long-term lease.
Open a Kasikorn Bank (KBank) account in week one
Apr 10, 2026Siam Paragon / Asok · Experience date Apr 3, 2026
KBank is the most foreigner-friendly Thai bank. Open at any branch with your passport and Non-Immigrant visa (tourist visas sometimes work but non-immigrant is safer). The KBank mobile app (K PLUS) is excellent for transfers and QR payments. Bring a local address — your hotel name and address is acceptable for the first account. The Siam Paragon and Asok branches are well-practiced with expats and have English-speaking staff.
Register your 90-day report online — don't miss it
Apr 6, 2026City-wide · Experience date Mar 30, 2026
Most foreign nationals staying over 90 days must file a 90-Day Report to Immigration. The online system at extranet.immigration.go.th is functional but unreliable — start the process 7 days before your deadline. If the online system is down, go in person to your nearest Immigration office with your passport. Missing the deadline triggers a 2,000 THB fine and can complicate future extensions.
Nearest hospital orientation — do this in day 2
Mar 25, 2026Thonglor · Experience date Jan 24, 2026
Bangkok has a two-tier medical system: elite private hospitals (Bumrungrad on Sukhumvit 3, Samitivej on Sukhumvit 49, BNH near Sala Daeng BTS) and government hospitals (cheap, long queues). Register a preference before you need it: walk into the nearest private hospital clinic, bring passport and insurance card, and request a patient registration. 15 minutes of paperwork now saves hours when you're sick. Find your nearest Bumrungrad or Samitivej and walk through their registration process in week one.

Mar 23, 2026Sukhumvit · Experience date Feb 20, 2026
Must-have Bangkok apps: Grab (taxis and food delivery), KBank K PLUS (once you have an account), BTS SkyTrain (official BTS app for journey planning), MRT Blue Line app, Google Maps (very accurate for BTS/MRT routing), IQAir Bangkok (air quality), DTAC/AIS app (SIM management), Line (messaging — everyone in Thailand uses Line, not WhatsApp primarily). Secondary: Foodpanda, Tops Online, Lazada, Shopee. Line is critical — Thai landlords, doctors, and most services communicate via Line, not email or phone.
