Key Takeaways
- Most countries need a tax identification number before you can be paid properly, and it usually takes time to obtain.
- A bank account often requires proof of address, which requires housing, which sometimes requires a bank account. Plan the order.
- Keep every employment document from day one — you will need them for status applications years later.
- Understand what your employer covers before you spend: relocation, temporary housing and healthcare vary enormously.
- The first payslip is the moment to check tax code, deductions and pension enrolment, not six months later.
Before you travel
Everything below is easier done at home than fixed from abroad.
Confirm your start date and exactly what the employer provides.
Relocation allowance, temporary housing, flights, visa costs, and whether any of it is reimbursed rather than paid upfront — the difference matters if you cannot front it.
Get documents certified before you leave. Degree certificates, transcripts, birth certificate, professional qualifications, driving licence. Certified copies and official translations are far harder to obtain once you are in another country, and you will be asked for at least one of them.
Bring more copies than you think. Physical and digital. Passport, visa, contract, qualifications, references, vaccination records, and passport photographs — which are needed surprisingly often and cost more abroad.
Sort a phone number early and keep your home number active for a while if you can; verification codes for existing accounts still go there.
Set up a way to move money before you need it. Standard bank transfers are expensive and slow; specialist services are cheaper. Test one with a small amount before relying on it for a rent deposit.
Tell your home bank you are moving, or your card gets blocked in your first week — a reliable and entirely avoidable disaster.
Check what your visa actually permits. Hours, employer restrictions, dependants, travel in and out. Read the conditions rather than assuming.
And build a buffer. More on that below, and it is the single most under-planned part of moving.
The order of operations problem
There is a circular dependency in most countries: a bank account needs proof of address, an address needs a rental agreement, and a rental agreement often needs a bank account or local employment.
How people break the loop:
- Employer letter. A letter confirming employment and salary substitutes for a lot of documentation. Ask HR on day one; they issue these constantly.
- Temporary accommodation with paperwork. Some serviced apartments and employer-arranged housing provide address documentation that banks accept.
- Digital banks first. In several markets, app-based banks open accounts with lighter documentation, then the traditional bank follows once you have a payslip and address.
Ask a colleague who arrived recently. Someone in your team did this within the last two years and knows which bank is straightforward for new arrivals.
Tax and payroll
Every one of these countries has an identifier you need before payroll works properly.
United States. A Social Security Number is required for employment. Apply as soon as you are eligible — processing takes time and payroll problems compound. Understand federal, state and local taxes; state income tax varies enormously and is why the same salary is worth different amounts in different cities.
United Kingdom. A National Insurance number is needed, though you can usually start work while the application is processing. Watch your tax code — new arrivals are frequently put on an emergency code and overpay, which is recoverable but only if you notice.
Canada. A Social Insurance Number is required before you can be paid. Federal and provincial tax both apply, and provincial rates differ significantly.
Singapore. A tax reference number is needed. Note that CPF contributions apply to citizens and permanent residents but not to Employment Pass holders, which changes what a headline salary means — worth understanding when comparing offers.
Check your first payslip properly. Tax code, deductions, pension or retirement enrolment, and whether the gross matches your offer. Errors in month one are easy to fix and awkward at year end.
Healthcare
Varies more than anything else on this list.
US. Employer-provided insurance is standard, with an enrolment window you must not miss. Understand the deductible, what is covered, and whether your doctor is in network. This is the largest and most confusing difference for arrivals from countries with public systems.
UK. NHS access, usually with an immigration health surcharge paid as part of the visa. Register with a GP early — before you need one, because registration takes time.
Canada. Provincial coverage, sometimes with a waiting period after arrival. Employers often provide supplementary insurance for what the public system does not cover.
Singapore. Employer medical benefits are usual; understand what is covered and whether dependants are included.
Documents to keep from day one
This looks like filing advice and it is one of the higher-value habits available to you, because status applications years later ask for details nobody can reconstruct.
Keep one folder, not on a work device, containing:
- Your employment contract and every amendment, with exact dates and job title as written
- Every payslip. All of them. Proof of income is requested for housing, credit, and immigration applications
- Your annual tax documents
- Every immigration document — visa, permit, entry stamps, and any correspondence
- Your supervisor's full name, title and a personal email where you have one, updated when they leave
- A one-paragraph description of what you actually did, written while it is fresh and updated yearly
- Proof of address history — tenancy agreements, utility bills. Several countries ask for a continuous address history in residence applications
- Travel dates in and out of the country. Some applications require a complete list, and reconstructing five years of trips from memory is genuinely difficult
Ten minutes a quarter. The alternative is discovering a gap at the moment it matters most, with an employer that no longer exists and an HR system that has been replaced.
The first month at work
Confirm what is actually covered. Relocation reimbursement deadlines, temporary housing end dates, and whether anything requires receipts you are about to throw away.
Register wherever local law requires. Some countries require residents to register an address with a local authority within a set period, with penalties for missing it. Ask a colleague — this is exactly the kind of thing that is obvious to locals and invisible to arrivals.
Sort transport. Season passes, a local driving licence if you need one, and whether your existing licence is valid and for how long.
Ask a colleague who moved recently for the practical list. Which bank was easiest, which neighbourhoods are reachable from the office, what nobody tells you. Twenty minutes with someone who did this eighteen months ago is worth more than any guide, including this one.
Expect the adjustment to be real. Competence at work and competence at life are separate, and being suddenly bad at buying a phone contract or understanding a payslip is disorienting for people who are used to being capable. It passes in a few months, it is close to universal, and knowing that in advance takes most of the sting out of it.
And be patient with the first quarter. You are learning a job and a country simultaneously, which is genuinely harder than either alone. The first ninety days are demanding for domestic graduates too — the difference is that you are doing it while also working out how the health system operates.
Money in the first two months
The part that surprises people, and the reason a good salary can still mean a difficult first quarter.
Expect a gap between arriving and being paid. Payroll cycles mean your first payment can be four to six weeks after you start, and sometimes longer if a tax number is delayed. Plan to fund yourself for that period with no income.
Rental deposits are often large. Several weeks or months of rent, plus agency fees in some markets, all payable before you move in — and typically before your first payslip exists.
Setup costs accumulate. Furniture, deposits for utilities and phone contracts, transport passes, and the small everyday things you owned at home and now do not.
Currency transfers cost more than you expect. Both the fee and the exchange margin. Moving a deposit at a bad rate through a bank can cost a meaningful fraction of it.
Your first payslip may be wrong. Emergency tax codes, incorrect starting assumptions and missing tax numbers are common. Check it properly in the first month — the tax code, the deductions, whether pension enrolment happened, whether the gross matches your contract. Correcting an error in month one is administrative; discovering it in month eight is a refund process.
A realistic buffer is two to three months of total living costs, available before you travel. That number sounds conservative and it is roughly what the gap actually requires once a deposit, a payroll delay and setup costs land in the same six weeks.
The order-of-operations problem, solved
The circular dependency that catches nearly everyone: a bank account needs proof of address, an address needs a rental agreement, a rental agreement frequently needs a local bank account or proof of employment, and your employer needs bank details to pay you.
The way through, in order:
1. Your employment contract is your most powerful document. It is proof of income, proof of employment and frequently proof of intent to reside. Bring several copies and a digital one. Many of the doors below open with it alone.
2. Ask your employer what they can provide before you arrive.
A letter of employment addressed to a bank or landlord, temporary accommodation, a relocation contact, or an introduction to a bank they have a relationship with. Large employers frequently have all of this and mention none of it unless asked.
3. Get a local phone number early. Almost every subsequent step wants one — verification codes, appointment bookings, delivery. A prepaid SIM on arrival is usually enough to start, and it unblocks more than you expect.
4. Temporary accommodation first, permanent second. Do not try to sign a long lease from overseas. Two to four weeks of temporary accommodation gives you an address to use and time to see neighbourhoods before committing.
5. Tax identification number as early as possible. In most countries you cannot be paid correctly without one, and obtaining it takes time. Start on your first working day, not your first payday.
6. Bank account, using the contract and temporary address. Some banks accept an employer letter in place of a permanent address; ask which ones before queuing at the wrong branch.
7. Permanent housing. Now you have a bank account, a number and a payslip or contract to show.
Where the order genuinely varies, ask a colleague who moved recently rather than reading a general guide. Someone who did it eighteen months ago knows which bank accepts what, and that specific knowledge saves days.
Tax, payroll and healthcare by country
The specifics differ enough that a general description is not actionable. Verify current requirements with the official authority — these change, and the point here is to show you what to go and check.
United States. You need a Social Security Number to be paid correctly and to file taxes; applying takes time and generally requires being in the country with your documents. Tax is withheld from each paycheck based on the form you complete when you start, so completing it carelessly produces a wrong withholding all year. Health insurance is usually via your employer, with coverage frequently starting on a defined date rather than day one — check whether there is a gap and whether you need cover for it. Retirement contributions are typically opt-in with an employer match; not enrolling forfeits money.
United Kingdom. You need a National Insurance number, and you can usually start work before it arrives provided you tell your employer. Tax is deducted through PAYE, and new arrivals are frequently put on an emergency tax code initially — which overcharges you and is corrected once your record is right. Healthcare is via the NHS; most visa holders pay an immigration health surcharge as part of the visa application. Workplace pension enrolment is automatic and opting out means declining an employer contribution.
Canada. You need a Social Insurance Number, obtainable fairly quickly with the right documents. Tax is deducted at source, split federal and provincial, so the rate depends on where you live. Healthcare is provincial, and several provinces impose a waiting period before coverage begins — which is exactly the gap where private cover matters.
Singapore. Employers handle tax filing arrangements for pass holders, and tax is generally not deducted monthly, which means you must set money aside for a bill rather than assuming your take-home pay is yours. CPF applies to citizens and permanent residents and not to work pass holders, which changes take-home pay considerably between two otherwise identical offers. Employers are typically required to provide medical insurance for pass holders — confirm what it actually covers.
In all four: check your first payslip properly. Tax code, deductions, pension enrolment, and whether gross matches your contract. Errors in the first month are administrative; the same error found in month eight is a refund process.
A timeline for the move
Everything on this page, in the order it needs doing.
Two months before. Confirm exactly what your employer provides and what is reimbursed rather than paid. Get documents certified and translated at home. Tell your bank you are moving. Set up and test a money-transfer service with a small amount.
One month before. Book temporary accommodation for two to four weeks — not a permanent lease. Read your visa conditions properly. Assemble the document folder, physical and digital. Confirm your buffer: two to three months of total living costs, available.
Week one on the ground. Local phone number. Start the tax identification application — day one, not payday. Open a bank account using your contract and temporary address. Register with the local authority if your country requires it.
Weeks two to four. View neighbourhoods, then sign a permanent lease. Sort transport and any licence conversion. Confirm when your healthcare coverage actually starts and cover any gap.
First payslip. Check the tax code, the deductions, the pension enrolment and whether gross matches your contract. Fix errors now.
Ongoing, ten minutes a quarter. File the payslips, keep the immigration documents, note travel dates in and out, and keep your supervisor's personal contact current.
The pattern worth noticing: nearly everything difficult in the first month is downstream of something that could have been done at home for free. The move is much easier for people who did the two-months-before column than for people who arrived and started from there.
Things nobody warns you about
Small, universal, and absent from every relocation guide.
Your credit history does not travel. You may have a decade of good standing at home and be treated as brand new on arrival — declined for a phone contract, asked for a large rental deposit, unable to get a normal credit card. This is not a reflection on you and it is worth expecting. It usually resolves within a year of local payslips and bills.
Deposits and guarantors. Some rental markets ask arrivals for six months upfront or a local guarantor. Ask your employer whether they act as one, because some do and almost none mention it.
Address proof is a bottleneck for months. Everything wants it and it takes weeks to accumulate. Keep every bill and letter with your name and address on it, physically.
Postal mail still matters. Tax numbers, bank cards and immigration documents arrive on paper. If you move between temporary and permanent housing, arrange forwarding, and never let a document go to an address you have already left.
Public holidays close things unexpectedly. Arriving the week of a major holiday can add ten days to every administrative task. Check before booking flights.
Your qualifications may need certification for non-work purposes too
— renting, professional registration, further study. Certified copies obtained at home are cheap; obtaining them from abroad is not.
And you will be bad at ordinary life for a while. People who are highly competent at work find it disorienting to be defeated by a ticket machine or a payslip. It is close to universal, it passes in a few months, and knowing it is coming takes most of the sting out of it.
Common Mistakes
- Not applying for the tax number immediately. It delays or complicates payroll.
- Assuming the employer arranges everything. Some do a great deal, some do almost nothing, and the difference is knowable in advance.
- Not checking the first payslip. Emergency tax codes and enrolment errors are common and easy to miss.
- Discarding payslips. They are required years later for status applications.
- Missing the health insurance enrolment window. In the US especially, this is a real and costly deadline.
- Underestimating the cash gap before the first payday. The most common practical difficulty for new arrivals.
When to ask your employer for help
Employers provide more than they advertise, and almost none of it is offered unprompted.
Ask before you sign, or shortly after. Relocation support is easiest to arrange when they are still recruiting you.
Worth asking about specifically: a letter of employment addressed to banks and landlords; temporary accommodation for the first few weeks; whether they have a relationship with a particular bank; a relocation allowance and whether it is paid upfront or reimbursed; help with the tax number registration; and whether anyone in HR has done this for an international hire before.
Ask who the last international hire was, and whether you can speak to them. Twenty minutes with someone who did this eighteen months ago at the same company is worth more than any guide.
And ask what the start date flexibility is. Two extra weeks between arriving and starting work is frequently granted, costs the employer nothing, and makes the administrative sprint far less punishing.
Frequently Asked Questions
Can I open a bank account before I arrive?
Sometimes, with certain international and digital banks. It removes the biggest bottleneck, so it is worth checking before you travel.
How long until my first salary?
Commonly four to eight weeks after arrival, depending on start date and payroll cycle. Plan for the longer end.
What if my tax number has not arrived?
In some countries you can start work while it processes; in others payroll is blocked. Confirm with HR before your start date rather than after.
Should I keep my home country bank account?
Usually yes, at least initially. Closing it early creates problems for existing obligations and for transfers back.
Who do I ask about all this?
HR for anything employment-related, and a colleague who arrived recently for everything else. The second is usually more useful for the practical order of operations.
What is the single most important thing?
Keep every document. Everything else is recoverable; a missing five-year employment record when you are applying for permanent residence is genuinely painful.
