Pick your passport to see whether you can enter United States β and what it takes to stay.
Entry rules come from github.com/imorte/passport-index-data, updated 17 February 2026. They change without notice β confirm with the official immigration service before booking.
There is no post-arrival registration in the US: your I-94 record is your status. In the first weeks you need a Social Security number if work-authorised, or an ITIN if not. Then the local complication starts. Missouri expects a vehicle titled and registered within 30 days of establishing residency and wants a driver licence obtained as soon as residency is established; Kansas runs its own timetable and its own document list. Both states require proof of lawful presence for a driver licence. Do not assume that because the two halves of the metro share a name they share a rulebook β they share almost nothing administratively, and the office you need is on the side of the line you live on, not the side you work on.
Read the full step-by-step guideMissouri expects a vehicle titled and registered within 30 days of establishing residency, and will not do it until the county assessor has issued you a Statement of Non-Assessment. Missouri also requires a safety inspection β but only for vehicles that are more than ten model years old OR over 150,000 miles; a newer, lower-mileage car is exempt from both conditions. There is no emissions testing anywhere in the Kansas City region: Missouri's Gateway programme covers only the St. Louis-area counties. Kansas requires no periodic safety or emissions inspection for ordinary cars but does require a VIN inspection for a vehicle titled out of state. The good news for a newcomer is that this is one of the cheapest and least bureaucratic driving regimes in this app; the catch is the assessor's office nobody mentions.
Read the full step-by-step guideYou can open a US account without a Social Security number: federal rules let a bank use your passport number and country of issuance, or an ITIN, as the identifying number. The credit problem is the standard American one β no US file scores worse than a bad one β and it lands hardest on the car loan, because outside a narrow downtown corridor a car is unavoidable here. The local wrinkle is payroll: in a bi-state metro your employer has to withhold for the correct state and, if you live or work inside Kansas City, Missouri, for the 1% earnings tax as well. Payroll departments get this wrong often enough that checking your first payslip line by line is a genuine local ritual.
Read the full step-by-step guideCoverage comes from an employer, from HealthCare.gov, or from Medicaid if your income qualifies β and here that last clause is decided by an address. Missouri voters put Medicaid expansion into the state constitution in August 2020 and it took effect in July 2021 after a Missouri Supreme Court ruling: adults aged 19 to 64 up to 138% of the federal poverty level are covered by MO HealthNet. Kansas has not expanded. A non-disabled adult under 65 with no dependent children has no KanCare pathway at any income, which is the coverage gap in its purest form. Neither state runs an exchange, so the federal deadline is the only deadline on both sides. Locally, the two dominant systems β Saint Luke's and the University of Kansas Health System β both operate across the line, but insurance networks do not always follow the geography.
Read the full step-by-step guideThe US has no SIM registration requirement, so getting connected is trivially easy: buy a prepaid SIM or eSIM and it works immediately. The friction is postpaid contracts, which run a credit check you cannot pass on arrival. Start prepaid, switch later once you have a file, and port the number rather than cancelling. The local advantages are real broadband competition β Kansas City was Google Fiber's first city and several addresses have three genuine options β and the local necessity is severe-weather alerting, because this metro sits in a real tornado corridor and the warnings arrive on the handset.
Read the full step-by-step guideAlmost nobody arrives here understanding this, and it is the most useful thing on the page. Missouri's individual income tax is graduated and tops out at 4.7%, with a full deduction for capital gains from the 2025 tax year. Kansas has two brackets β 5.20% and 5.58% β with a standard deduction far below the federal one, so Kansas taxable income runs higher relative to gross pay than the headline rate suggests. Neither state permits local income taxes generally, but Missouri grandfathers two: Kansas City and St. Louis. Kansas City, Missouri's earnings tax is 1%, charged on residents' whole earnings and on non-residents' earnings for work physically done inside the city limits, and voters renewed it on 7 April 2026 by roughly three to one, keeping it to 2031. If you cross the line to work you file two state returns and claim a credit; and since 2015 a Kansas resident may claim the Kansas City earnings tax as a credit on the Kansas K-40 too. On top of all that, both states tax your car every year.

This is not a nuance β it is the organising fact of the metro. Missouri's income tax is graduated and tops out at 4.7%; Kansas has two brackets at 5.20% and 5.58% with a much smaller standard deduction, so Kansas taxable income runs higher relative to gross pay. Missouri taxes your car every year as personal property; Kansas taxes vehicles too, collected with the tag. Kansas dropped the state sales tax on groceries on 1 January 2025 while Missouri still charges a reduced state rate on food. And Kansas City, Missouri levies a 1% earnings tax on top of whichever state you land in. Model your actual salary on both sides before you sign a lease. The answer is not obvious and it is worth thousands.
Kansas City, Missouri's earnings tax is 1% on residents' entire earnings and on non-residents' earnings for work physically performed inside the city limits. Voters renewed it on 7 April 2026 by roughly three to one, so it runs to 2031; it raises close to $374 million a year and is nearly half the city's general fund. The part almost nobody tells newcomers: a non-resident who works some days outside the city can reclaim the tax on those days using Form RD-109NR, which for a hybrid or remote worker is real money every year. And since 2015 a Kansas resident may claim the earnings tax as a credit on the Kansas K-40 β but only if they know to.
Missouri assesses personal property β cars, boats, trailers β as of 1 January each year, and the declaration is due to the county assessor by 1 March. If you moved here after 1 January you owe nothing for that year, but you cannot register a vehicle without proving it: you need a Statement of Non-Assessment, locally called a tax waiver, from the assessor of the county you live in. People discover this standing at the licence office. Get it first. Missouri also expects the vehicle titled and registered within 30 days of establishing residency.
Missouri voters wrote Medicaid expansion into the state constitution in August 2020 and, after a Supreme Court ruling, it took effect in July 2021: adults aged 19 to 64 up to 138% of the federal poverty level are covered. Kansas has not expanded, and a non-disabled adult under 65 without dependent children has no KanCare pathway at any income at all. That is the starkest thing about this metro. If your first months here are lean β a spouse not yet working, a contract that slipped β the Missouri side has a floor under you and the Kansas side does not.
The Social Security Administration verifies your status against DHS records that lag entry by one to two weeks, so going in on day two usually wastes the trip. Only work-authorised people qualify; everyone else files IRS Form W-7 for an ITIN. The card is free.
This is not Tornado Alley folklore β the metro sits in a genuine severe-storm corridor and the season runs roughly April to June. Outdoor sirens are tested at a fixed time each week; a siren outside that slot means go inside, to a basement or an interior room on the lowest floor, immediately. Ask on day one where the shelter is in your building, keep alerts switched on, and treat a tornado warning as different in kind from a watch. Newcomers from countries with no severe convective weather consistently under-react the first time.
Burns & McDonnell, Black & Veatch, HNTB, JE Dunn Construction, Terracon
An unusual concentration of large employee-owned engineering firms for a metro this size β Burns & McDonnell and Black & Veatch design power, water and infrastructure projects worldwide from offices here. It is the region's most distinctive white-collar sector and the one most likely to hire an engineer relocating internationally.
Boehringer Ingelheim Animal Health, Elanco, Merck Animal Health, Ceva, Bayer Crop Science, the Kansas City Animal Health Corridor
The corridor running from Manhattan, Kansas through Kansas City to Columbia, Missouri holds the largest concentration of animal health companies in the world β a genuinely globally significant cluster that almost nobody outside the industry has heard of. Kansas State's veterinary and biosecurity research anchors the western end.
The Kansas City National Security Campus operated by Honeywell FM&T, the Federal Reserve Bank of Kansas City, the IRS service centre, the USDA, the General Services Administration complex at Bannister
Kansas City is one of the largest federal employment centres outside Washington. The National Security Campus manufactures non-nuclear components for the National Nuclear Security Administration and is a large, stable, security-cleared employer; the Federal Reserve Bank here is one of the twelve district banks.
Saint Luke's Health System, the University of Kansas Health System, Children's Mercy Kansas City, HCA Midwest, Stowers Institute for Medical Research, Cerner sites now under Oracle Health
Children's Mercy is one of the country's leading paediatric hospitals and a genuine reason families choose this metro. The Stowers Institute is a privately endowed basic-research institute of a kind few cities have. Note that the health systems straddle the state line and insurance networks do not always follow.
Canadian Pacific Kansas City, BNSF, Ford's Kansas City Assembly Plant at Claycomo, General Motors Fairfax Assembly in KCK, the Kansas City SmartPort inland hub
Kansas City handles more rail freight tonnage than almost anywhere in the United States and sits at the crossing of four interstate highways. Two large car assembly plants β Ford on the Missouri side, GM on the Kansas side β anchor manufacturing employment, and CPKC's merger created the first single-line railway linking Canada, the US and Mexico.
Garmin in Olathe, T-Mobile's campus on the former Sprint site in Overland Park, H&R Block, Hallmark Cards, Cerner sites under Oracle Health, Commerce Bancshares, UMB Financial, Evergy
Kansas City was the first city in the world to get Google Fiber, in 2012, and the resulting broadband competition is still unusually real here. Garmin, Hallmark and H&R Block are all headquartered in the metro, and the old Sprint campus in Overland Park remains one of the largest single office sites in the region.
Culture Β· East of downtown, Missouri side
The historic centre of Kansas City jazz, where Charlie Parker grew up and Count Basie's band took shape, now home to the American Jazz Museum and the Negro Leagues Baseball Museum in one building.
Local tip: The Negro Leagues Baseball Museum is the reason to come and it is one of the best small museums in America β allow two hours, not one. The Blue Room next door is a working jazz club rather than a heritage exhibit, and Mutual Musicians Foundation up the street still runs a jam session that starts after midnight on weekends.
Neighborhood Β· About five kilometres south of downtown
A 1922 Spanish-revival shopping district built with towers, tiled fountains and a car in mind β the first of its kind anywhere β with the leafy Brookside and Waldo neighbourhoods running south from it.
Local tip: The streetcar now runs here from downtown and it is free, which changes how the Plaza works for anyone without a car. Come the evening of Thanksgiving for the lights switch-on if you want to understand the city, and any other evening if you want to park.
Culture Β· Between the Plaza and UMKC
A major encyclopaedic art museum with a world-class Asian collection and a Steven Holl glass extension, sitting on a lawn with four giant badminton shuttlecocks on it. Admission to the permanent collection is free.
Local tip: The lawn is a genuine public park and people picnic on it all summer. Go into the Bloch Building at dusk when the glass lanterns light from within β it is the best twenty minutes of architecture in the region and it costs nothing.
Food Β· Downtown, on the Missouri River bluff
A public market trading since the 1850s at the northern end of downtown, with a large Saturday farmers' market, a permanent ring of Middle Eastern, Vietnamese and Mexican grocers, and the free streetcar at the door.
Local tip: Saturday morning is the full version and it is genuinely busy. The permanent shops on the perimeter are open all week and are where to buy spices, bread and produce you cannot get in a supermarket here.
Landmark Β· Liberty Memorial, just south of downtown
America's official First World War museum, under a 1926 memorial tower on a bluff, with a glass bridge over a field of nine thousand poppies and the best view of the downtown skyline in the city.
Local tip: The tower observation deck is a separate small charge and worth it. Go late in the afternoon so you get the skyline in the last light β it is the photograph everyone takes of Kansas City, and almost nobody who lives here has been up.
Nightlife Β· Between downtown and the state line
The old stockyards district of cast-iron warehouses below the bluff, and the gallery-and-restaurant Crossroads just south of downtown, which holds a First Fridays art walk that shuts the streets.
Local tip: First Fridays in the Crossroads is the easiest social entry point in the city for a newcomer β free, crowded, and the galleries genuinely open. The West Bottoms is quieter, mostly antique warehouses, and is best on a weekend afternoon.
