## Provenance policy

Facts on this page are taken from the sources listed above — U.S. federal agencies, state governments, regulators and official statistical releases. Comparisons, judgments and "which option suits whom" conclusions are AI-assisted analysis written over those sources; they are marked in the text and listed as an AI-analysis entry in the sources, not attributed to any authority. Rates, thresholds, fees and processing times change, often at the start of a calendar or tax year; figures are current as of the review date shown and should be confirmed with the responsible agency before you rely on them. A great deal of American law is state law — where a rule differs by state, this site says so.

Each page lists its sources with a `kind` badge (official, law, regulator, statistics, research, news, industry). Passages that are AI-assisted reasoning rather than cited fact are shown in a labeled callout on the page and repeated as an explicit `AI analysis` entry in the source list. When quoting this site, please carry that distinction through.

## About the USA

- [A short history of the United States](https://usainfohub.com/usa/history-of-the-united-states): Indigenous nations, colonization, a revolution, a constitution, a civil war fought over slavery, a century of segregation, a civil rights movement, and the superpower era. The compressed version, with the events that still shape American politics.
- [American culture and etiquette, for people who did not grow up here](https://usainfohub.com/usa/american-culture-and-etiquette): Direct where Britain is indirect, friendly without being familiar, obsessed with tipping and small talk, and governed by unwritten rules about work, money, punctuality and personal space that nobody explains. What is actually expected.
- [Federalism explained — why the answer depends on your state](https://usainfohub.com/usa/federalism-explained): Almost every confusing thing about American paperwork traces back to one clause written in 1787. This explains what the federal government can and cannot do, why fifty states produce fifty answers, and how to work out which government owns your problem.
- [The cost of living in the USA](https://usainfohub.com/usa/cost-of-living-in-the-usa): High incomes, high housing costs, and the two expenses that make American budgeting genuinely different from anywhere else: health insurance and a car. A realistic breakdown of where the money goes, and what varies most by state.
- [How the US government works](https://usainfohub.com/usa/how-the-us-government-works): Three branches designed to frustrate each other, a legislature where the minority can block almost anything, a president chosen by state rather than by national vote, and a court with lifetime appointments. How it actually functions.
- [The US economy — what America actually earns from](https://usainfohub.com/usa/us-economy-explained): The world's largest economy at roughly $29 trillion, dominated by services, running on consumer spending, and unusual among wealthy nations for how much of household finance is left to the individual. What it produces and what the arguments are about.
- [The US legal system, and the rights it actually gives you](https://usainfohub.com/usa/the-us-legal-system-explained): Two parallel court systems, fifty-one bodies of law, a written Bill of Rights that binds government but not private companies, and a litigation culture built on the fact that each side pays its own lawyers. How it works and where to get help.
- [The USA's climate and environment](https://usainfohub.com/usa/climate-and-environment): The only country with essentially every climate type on earth, and consequently with essentially every natural hazard. What the regional climates actually are, where hurricanes, tornadoes, wildfires and earthquakes concentrate, and how to check risk before you move.
- [America's flag, anthem, symbols and federal holidays](https://usainfohub.com/usa/symbols-and-national-holidays): A flag that has changed 27 times, an anthem that was a drinking song, a pledge written by a socialist minister, and eleven federal holidays that most private workers have no right to take off. What each thing means and why.
- [US states and territories — and why the differences matter](https://usainfohub.com/usa/states-and-territories-of-the-usa): Fifty states, one federal district and five inhabited territories, each with its own laws, taxes, licensing and courts. What each region is, what changes when you cross a state line, and the territories most Americans could not name.
- [What is the United States — country, federation and system](https://usainfohub.com/usa/what-is-the-united-states): A federal republic of 50 states and about 342 million people, spanning six time zones and every climate on earth, governed under the oldest written national constitution still in force. Here is what that actually means in practice.
- [Who lives in the USA](https://usainfohub.com/usa/people-and-population): About 342 million people, 13.6 percent born abroad, growing almost entirely through immigration, and becoming both more multiracial and less religious. What the 2020 Census and subsequent data actually show.

## Arriving & settling in

- [How to open a US bank account](https://usainfohub.com/guides/how-to-open-a-us-bank-account): No federal law requires a Social Security number to open an account — banks require identification, and an ITIN or foreign passport satisfies many of them. What to bring, which institutions say yes to newcomers, and the fees worth refusing.
- [Moving to the USA — your first 30 days, in the right order](https://usainfohub.com/guides/moving-to-the-usa-first-30-days-checklist): Six things unlock everything else: an address, a phone number, a Social Security number, a bank account, health insurance and the start of a credit file. Done in the wrong order each one blocks the next. This is the sequence that works.

## Government services & ID

- [How to get a Social Security number](https://usainfohub.com/guides/how-to-get-a-social-security-number): An SSN is free, permanent and issued only by the Social Security Administration. This covers who is eligible, how to apply as a new arrival, what to do if you are not eligible, and how to protect a number that cannot be changed.

## Money, tax & credit

- [How to build credit from zero](https://usainfohub.com/guides/how-to-build-credit-in-the-usa): A credit score gates renting, borrowing, insurance pricing and sometimes employment — and arriving with a perfect record from another country counts for nothing. This is how the score is actually calculated and the fastest legitimate way to build one.
- [How to file a US tax return](https://usainfohub.com/guides/how-to-file-a-us-tax-return): Federal returns are due April 15, most people can file free, and state returns are separate. This covers who must file, the free filing options the IRS does not advertise well, the credits people miss, and what to do if you cannot pay.
- [Understanding your US paycheck](https://usainfohub.com/guides/understanding-your-us-paycheck): Gross to net in America involves federal tax, FICA, state tax, possibly city tax, insurance premiums and retirement contributions. What each line means, why your take-home is lower than you expected, and how to fix withholding that is wrong.

## Work & employment

- [What to do if you are fired or laid off](https://usainfohub.com/guides/what-to-do-if-you-are-fired-or-laid-off): File for unemployment the same week — being fired does not automatically disqualify you. Then health coverage, where the Marketplace is usually far cheaper than COBRA. Plus the severance agreement you should not sign immediately.
- [Your rights at work in the USA](https://usainfohub.com/guides/your-rights-at-work-in-the-usa): At-will employment, a federal minimum wage frozen since 2009, no legal right to paid vacation or sick leave, and strong protection against discrimination and retaliation. What the federal floor is, what states add, and where to complain.

## Housing & renting

- [How to get your security deposit back](https://usainfohub.com/guides/how-to-get-your-security-deposit-back): Every state sets a deadline for returning a deposit and an itemized statement, and most impose penalties — often double or triple damages — for missing it. This explains the process, what counts as normal wear and tear, and how small claims court actually works.
- [How to rent an apartment in the USA](https://usainfohub.com/guides/how-to-rent-an-apartment-in-the-usa): American renting runs on credit scores, income multiples and application fees. This covers what landlords check, how to rent with no credit history, what a lease actually commits you to, and the fair housing rights that apply everywhere.

## Driving & transport

- [How to get a US driver's license](https://usainfohub.com/guides/how-to-get-a-us-drivers-license): Licensing is state law, so there are fifty sets of rules. This covers the common structure — permit, road test, license — plus converting a foreign license, the 30-to-90-day residency deadline, REAL ID, and the insurance you must carry before you drive.

## Health insurance & care

- [How to find affordable healthcare without insurance](https://usainfohub.com/guides/how-to-find-affordable-healthcare-without-insurance): Community health centers charge by income, Medicaid has no enrollment window, prescription prices vary wildly between pharmacies for the same drug, and emergency rooms must treat you. The real options, in order of what to try first.
- [How US health insurance actually works](https://usainfohub.com/guides/how-us-health-insurance-works): Premium, deductible, copay, coinsurance, out-of-pocket maximum, network. Six terms that decide what you actually pay, explained in the order they apply — plus where coverage comes from and what to check before choosing a plan.
- [What to do about a surprise medical bill](https://usainfohub.com/guides/what-to-do-about-a-surprise-medical-bill): Never pay a medical bill on first receipt. The No Surprises Act bans most out-of-network emergency billing, hospital charity care is legally required at nonprofits, medical debt has been stripped from credit reports, and billing errors are extremely common.

## Bills & utilities

- [How to set up utilities in the USA](https://usainfohub.com/guides/how-to-set-up-utilities-in-the-usa): Electricity, gas, water, trash and internet are separate accounts, deposits are demanded from anyone without credit history, and a minority of states let you choose your energy supplier. What to set up, how to dodge the deposits, and the help programs most people never claim.
- [What to do if you can't pay a bill](https://usainfohub.com/guides/what-to-do-if-you-cant-pay-a-bill-usa): Call before the due date, not after the shutoff notice. Which bills to pay first when you cannot pay all of them, the assistance programs that go unclaimed, and the debt collection rights most people never use.

## Education & study

- [How to enroll your child in a US public school](https://usainfohub.com/guides/how-to-enroll-your-child-in-a-us-public-school): Public school is free, assigned by home address, and open to every child regardless of immigration status — a constitutional right schools cannot condition on papers. What districts can and cannot ask for, how zoning works, and the free programs inside the system.

## Consumer rights & complaints

- [How to complain and actually win](https://usainfohub.com/guides/how-to-complain-and-actually-win-usa): America has no general ombudsman, but it has something almost as good: regulators whose complaints companies must answer, state attorneys general who mediate, chargebacks, and small claims court. The escalation ladder that works, and which channel fits which problem.

## Scams, safety & emergencies

- [How to report a scam in the USA — and try to get your money back](https://usainfohub.com/guides/how-to-report-a-scam-in-the-usa): Call your bank first, freeze your credit second — freezes are free by federal law and are the strongest protection available. Then report to the FTC and IC3. What each does, what it cannot do, and which payment methods are actually recoverable.

## Travel & things to do

- [The best things to do in the USA](https://usainfohub.com/guides/best-things-to-do-in-the-usa): A country the size of a continent, which makes the real skill choosing what to skip. An honest region-by-region shortlist, the national park system that is America's best cultural export, and the distances that break every first-timer's itinerary.

## Scams safety & emergencies

- [What to do if your identity is stolen](https://usainfohub.com/guides/what-to-do-if-your-identity-is-stolen-usa): IdentityTheft.gov generates a recovery plan and an official report creditors must accept. Freeze all three credit bureaus free, dispute fraudulent accounts in writing, and know that federal law caps your liability at almost nothing if you report promptly.

## Quick answers

- [Can I be fired without notice in the USA?](https://usainfohub.com/questions/can-i-be-fired-without-notice-usa): Yes, in 49 states. Employment is at-will: either side can end it at any time, for any lawful reason or no reason, with no notice and no severance required. What is illegal is firing for a protected reason — discrimination, retaliation, or exercising a legal right like discussing pay or taking FMLA leave.
- [Can I return something I bought in the USA?](https://usainfohub.com/questions/can-i-return-something-i-bought-usa): Only if the store's return policy allows it — there is no general legal right to return non-defective goods, and no cooling-off period for store or online purchases. Defective goods are different: implied warranty law applies in every state, and credit card purchases carry 60-day dispute rights.
- [Do Americans get paid vacation?](https://usainfohub.com/questions/do-americans-get-paid-vacation): Not by law — the US is the only wealthy country with no federal requirement for paid vacation, paid holidays or paid sick leave. Employers offer it voluntarily: around two weeks is the common starting norm, and about a fifth of private workers get no paid vacation at all.
- [Do I need a Social Security number to start work in the USA?](https://usainfohub.com/questions/do-i-need-a-social-security-number-to-work): You need work authorization, not the number itself, to start. Form I-9 — completed within three business days of your first day — verifies your right to work and does not require an SSN; the employer records that one has been applied for. Provide the number when it arrives so payroll and tax reporting are correct.
- [How long does it take to build credit in the USA?](https://usainfohub.com/questions/how-long-does-it-take-to-build-credit-usa): About six months of activity on at least one account before a FICO score exists at all. A year of on-time payments with low utilization typically reaches the high 600s; 740-plus — where the best loan pricing starts — generally takes two to three years. Foreign credit history transfers nothing.
- [How many states are in the USA?](https://usainfohub.com/questions/how-many-states-are-in-the-usa): Fifty, plus Washington D.C. — a federal district that is not a state — and five inhabited territories: Puerto Rico, Guam, the US Virgin Islands, the Northern Mariana Islands and American Samoa. Hawaii was the most recent state, admitted in August 1959, seven months after Alaska.
- [How much does health insurance cost in the USA?](https://usainfohub.com/questions/how-much-does-health-insurance-cost-usa): With employer coverage, the worker's share averages roughly $110 a month for single coverage and $525 for family, with employers paying the larger part of premiums that total over $8,000 and $25,000 a year respectively. Marketplace plans are income-subsidized — many enrollees pay under $50 a month after credits.
- [How much income tax do I pay in the USA?](https://usainfohub.com/questions/how-much-tax-do-i-pay-in-the-usa): Federal income tax runs through seven marginal brackets from 10 to 37 percent, applied only to income within each band after the standard deduction. Payroll taxes add 7.65 percent for Social Security and Medicare. State income tax ranges from zero in nine states to over 13 percent in California.
- [How much should I tip in the USA?](https://usainfohub.com/questions/how-much-should-i-tip-in-the-usa): 18 to 20 percent at restaurants with table service, $1–2 per drink at bars, 15–20 percent for taxis and rideshares, $2–5 per night for hotel housekeeping, and around 20 percent for haircuts. It is not optional in practice: tipped workers can legally be paid as little as $2.13 an hour in cash wages.
- [Is a credit freeze free in the USA?](https://usainfohub.com/questions/is-a-credit-freeze-free-usa): Yes — federal law has required Equifax, Experian and TransUnion to provide freezes, unfreezes and temporary lifts free of charge since September 2018, including for children. A freeze blocks new credit being opened in your name, does not affect your score, and lifts online in minutes when you need it.
- [Is healthcare free in the USA?](https://usainfohub.com/questions/is-healthcare-free-in-the-usa): No. There is no universal public system — coverage comes from an employer, a government program like Medicare or Medicaid, or a Marketplace plan, and even the insured pay deductibles and copays. Emergency rooms must stabilize anyone regardless of ability to pay, but they bill for it afterward.
- [What credit score do I need to rent an apartment in the USA?](https://usainfohub.com/questions/what-credit-score-do-i-need-to-rent): There is no legal threshold — mid-600s is a common informal floor, with competitive city markets expecting 700 or more. With no US credit history, compensating evidence works: proof of income at 2.5–3× rent, bank statements, a larger deposit where state law allows, or a co-signer.
- [What is the emergency number in the USA?](https://usainfohub.com/questions/what-is-the-emergency-number-in-the-usa): 911, for police, fire or ambulance anywhere in the country — free from any phone, including a locked cell phone with no service plan. For mental health or suicidal crisis, call or text 988. For poison exposure, 1-800-222-1222. For non-emergency local help with rent, food or utilities, dial 211.
- [When is the US tax filing deadline?](https://usainfohub.com/questions/when-is-the-us-tax-deadline): April 15, for the previous calendar year, moving to the next business day when it falls on a weekend or holiday. Form 4868 grants an automatic six-month filing extension to October 15 — but it does not extend the time to pay, and interest runs on unpaid tax from April 15.
