Moving abroad: a 30-day countdown, week by week

Why a countdown beats a long checklist

Moving abroad is not one task; it is forty small tasks that depend on each other. You cannot book a one-way ticket sensibly before you know your permit timeline, you cannot close a Thai account before the last transfer lands, and you cannot cancel your phone contract before you know which number your bank will text. A countdown puts those dependencies in order, so each week has a theme and you can see at a glance whether you are on track.

This plan assumes you are a Thai resident leaving for a stay of several months or longer, for work, study or family. The exact documents depend on the destination, so treat each item as a prompt to check the official source, not as a rule.

Days 30 to 22: lock down the paperwork

Start with whatever has an external clock. Check how long your passport remains valid and whether the destination expects extra validity beyond your stay; renewing a Thai passport takes appointments and processing time, so this cannot wait. Then confirm the exact permit or visa route, who files it, and whether you must apply before departure or can convert status after arrival.

• Passport validity, blank pages and any name differences between documents.
• Visa or permit application status, and which documents must be originals, translated or legalised.
• Certified copies of degree, marriage, birth or employment documents if the destination or employer asks for them.
• Driving licence: whether your Thai licence is accepted, needs translation, or must be swapped locally.

Photograph or scan every document the moment it is in your hands. Store one copy in encrypted cloud storage and one on a device you will carry, and give a trusted family member a set too.

Days 21 to 15: money, insurance and your Thai obligations

Money decisions have the longest lead times because banks and transfers are slow. Decide how you will fund the first two or three months before your first local income or allowance arrives, and in which currency. Ask your Thai bank which of your cards work abroad, what happens to online banking and one-time passwords when you are outside Thailand, and whether you can still approve transfers from overseas.

• Tell your banks and card issuers about the move, and ask about foreign transaction charges and daily limits.
• Carry a small amount of destination currency for the first day, and keep the rest in cards or accounts you can reach.
• Ask an adviser or the Revenue Department how leaving affects your Thai tax residence, rather than guessing.

Insurance deserves its own decision. Check whether the destination or your employer or school requires health cover, whether a Thai policy still applies once you live abroad, and what the insurer says about pre-existing conditions. Ask the insurer directly; do not rely on a summary on a website, including this one.

Days 14 to 8: phone, number and accounts

Your phone number is quietly attached to far more than you realise: bank apps, government services, delivery apps, messaging accounts, two-factor codes. Before you do anything to the SIM, list every service that sends you a code. Decide which of those must keep your Thai number and which you can move to an email or authenticator app.

• Check your operator's rules for keeping a number active while you are away, including any minimum top-up or expiry period, and write them down.
• Switch important accounts to an authenticator app or email where the service allows, and save recovery codes offline.
• Back up the phone, and confirm that it is not locked to a Thai carrier or managed by an employer profile.

See the guide on keeping your Thai number while living abroad and the one on calls, SMS and one-time passwords on roaming for how the pieces fit together.

Days 7 to 3: housing, packing and the paper trail

By the last week you should know where you will sleep for the first nights, even if it is temporary. Keep the booking confirmation and the address in the local script and in English, because a taxi driver or immigration officer may ask. If you are leaving a Thai home or rental, settle utilities, hand over keys with a written record and photograph the condition.

• Carry-on: passport, permits and printed originals, a payment card, medicines in original packaging with the prescription, chargers, one change of clothes.
• Check the airline baggage allowance and the destination's rules on medicines, food and cash before you pack, not at the counter.
• Ship or store what you will not carry, and keep the receipt and tracking number with your documents.

Your countdown at a glance

Staying connected from the moment you land

Your first hours are when you most need a working phone: confirming a pickup, opening a map, showing a booking, receiving a bank code. Airport Wi-Fi often needs a sign-in or has limits, and a local SIM may mean a queue and paperwork while tired. A travel eSIM installed before you fly is one practical way to have data on arrival, provided your phone supports eSIM and is unlocked. Whether it connects depends on the destination network and your device, and nobody can guarantee it, so keep a fallback such as offline maps.

Keep your Thai SIM in the phone as the second line if you can. It lets bank and government text messages keep arriving while the data plan handles the internet. For longer stays, read the guide on long-stay connectivity, which covers when to move from a travel plan to a local one.

Things people forget

• Subscriptions and memberships tied to a Thai card or address, which may fail or change price once you leave.
• Mail: arrange forwarding or a trusted person to open official letters.
• Vaccination and medical records, and glasses or lens prescriptions.
• Power plugs and voltage for chargers and appliances you plan to carry.
• A written list of emergency contacts at home and at the destination, saved offline.
