| Home bank account | Keep it. Prepare the continuity kit 3 to 6 months before you leave, while address changes and second-factor swaps are easy. | Your financial history, your savings under deposit insurance, and the anchor for anything that still lives in your home country: taxes, subscriptions, family, an eventual return. | Address and returned-mail triggers, SMS-only logins tied to a dead number, dormancy from disuse, and banks that quietly restrict customers who report a foreign address. |

| Multi-currency e-money account | Open before you fly. Verification is simpler from your home country, and you want the card in hand on day one. | The border-crossing layer: holding several currencies, converting near mid-market rates, receiving pay in one currency and spending in another. | Commonly safeguarded rather than deposit-insured, so keep working balances, not savings. Feature sets and protections vary by provider and by the country where you signed up. |
|---|
| Local bank account | Open after arrival, once the residence permit, address registration, and local tax ID exist. Usually weeks in, not day one. | Rent, utilities, salary in some countries, and the local payment systems that only speak to domestic accounts. | Usually cannot be opened before the residence paperwork exists, so do not build your first month's budget around having one. Requirements vary widely by country and by bank. |
