The international travel checklist for first-timers and repeat travelers
International travel is forgiving until it isn't. You can wing most domestic trips; international, you can't. One missed step (no visa, expired passport, no yellow fever vaccine) and you're refused boarding or detained on arrival. This checklist covers everything — passport, visa, health, money, tech, documents — organized by category with actual lead times and 2026 prices.
Passport + visas (start 90 days before)
Passport validity: 6 months past return date for most international destinations. Minor exceptions (Canada, UK, Caribbean accept through return date). Renew: routine $130 + $35 execution = $165, 8–11 weeks. Expedited: +$60 fee + $25 1–2 day delivery = $250 total, 4–6 weeks. In-person at Passport Agency: same-day if flying within 14 days, requires appointment on travel.state.gov. Visas: check embassy website of destination. Common requirements: India (e-visa $25–$80 for 60 days, 72-hour processing), China (90+ day processing, requires in-person biometrics for some nationalities — 2026 process tightened), Brazil (e-visa returned 2025 for US/Canada/Australia, $81), Russia (complicated, expensive, current political context). Schengen visa for non-U.S. passports visiting Europe ($70–$100, 15 business days). ETIAS for U.S. passport visiting Europe: $8/€7, online, takes up to 4 business days, required starting mid-2025.
Health + vaccinations (start 60 days before)
Check CDC travel health page for your destination. Routine vaccinations: MMR, Tdap, flu, COVID-19 boosters all current. Destination-specific: Yellow Fever (required entry in many African and South American countries, some Asian — $160 at travel clinic, certificate stamped in yellow book). Typhoid (South Asia, SE Asia rural, $180). Japanese Encephalitis (rural Asia, $320 for 2-dose series). Rabies (extensive rural travel, $280–$380 for 3-dose series). Hep A/B (most tropical destinations, $320 for combo series). Malaria pills: prescription required. Malarone is first-line ($5–$8/pill, take 1/day during + 7 days after), doxycycline ($0.50–$1/pill, take during + 4 weeks after) is cheaper but sun-sensitivity side effect. Chloroquine still works in some areas. Travel clinic comprehensive visit: $120–$200 consultation + vaccines. Get vaccines 4–6 weeks before departure (some series need multiple doses or activation time).
Money + payments
Primary credit card: 0% FX + travel perks. Top picks: Chase Sapphire Preferred ($95 AF), Capital One Venture X ($395), Amex Gold ($325), Bilt (no AF). Backup credit card different network (if primary is Visa, backup is Mastercard/Amex). Hidden backup in separate bag. Debit card for ATM cash: Charles Schwab High Yield Investor Checking refunds all worldwide ATM fees — the single best travel banking product in the U.S. Fidelity Cash Management similar. Notify bank/card company of travel dates (Chase/Amex usually don't need notification; BofA/Wells Fargo still do). Set PIN to 4 digits (many foreign ATMs reject 6-digit). Small cash in local currency: $100 equivalent, obtained at first arrival ATM not at airport exchange (airport exchange rates are 10–15% worse).
Tech + communication
Cell service options: Airalo eSIM (global coverage, 10 GB / 30 days global plan $30, regional plans cheaper) — activate on arrival. T-Mobile Magenta plan: unlimited international data at 2G speeds (slow but free), 5G in 40+ countries with $35 international day pass. Verizon TravelPass: $10/day in 210+ countries.

Navigation: Google Maps offline downloads for each city.
Documents + insurance
Travel insurance: 5–7% of non-refundable trip cost. Coverage categories: trip cancellation (medical reason, family emergency, job loss), medical evacuation ($50,000–$250,000 recommended), lost luggage ($500–$2,500 per bag), trip delay ($1,000+ meals + hotel), emergency medical ($100,000–$500,000).

Printed itinerary + hotel confirmations. Emergency contact card with embassy numbers, insurance policy number, credit card loss-reporting numbers.
Packing specific to international
Voltage converter: most laptop/phone chargers auto-switch 110–240V. Hair tools, some medical devices don't — check wattage. Plug adapter: universal (Epicka $25). First aid kit: ibuprofen, Tums, Imodium, Pepto, Benadryl, Band-aids, hydrocortisone, rehydration salts, emergency antibiotics (Cipro prescription from your doctor — common for South Asia). Feminine hygiene products (limited availability abroad). Prescription meds in original bottles with prescription copy. Clothing for destination + culture (modest cover-ups for temples/mosques/Mediterranean churches).
Arrival procedures
At immigration: have passport, return ticket, hotel address ready. Answer questions briefly and truthfully ("visiting for tourism, staying 10 days at [hotel]"). Customs declaration: know what you're carrying (food restrictions vary; US $10,000+ cash must be declared in either direction). ATM in arrival hall: use a major bank ATM, not a kiosk. First SIM card: activate eSIM before leaving the airport (needs Wi-Fi). Transport from airport: research before — ride-share, train, airport bus. Avoid unlicensed taxis in unfamiliar airports (Moscow, Delhi, Nairobi are notorious).
During your trip
Daily: check STEP/travel advisory updates. Photograph receipts (budget tracking + expense reports). Charge phone + power bank every night. Replenish cash at ATM as needed. Check credit card app for unauthorized charges. Hotel safe: use for passport when not needed. Wear passport in hidden belt when crossing borders by land.
FAQ on international travel
What's the biggest rookie international mistake? Assuming your domestic credit card will work everywhere with no fees. Most non-travel-specific cards charge 3% FX fee. Use a 0% FX card or you're overpaying 3% on every purchase. Should I get yellow fever vaccine if my destination doesn't require it? Usually not — it's only needed if you're traveling from an endemic country to another that requires proof, or staying in malarial zones. Visa on arrival or eVisa? eVisa is safer (approved before you fly). Visa on arrival works but depends on airline also accepting. Prescription medications abroad? Keep in original labeled bottles + prescription copy. Some narcotics/controlled substances are illegal in countries where they're legal at home (ADHD stimulants restricted in Japan; Mexico has its own rules). Check International Narcotics Control Board before traveling. What if I lose my passport abroad? Report to local police (get police report), go to nearest U.S. embassy/consulate. Emergency passport $165, 2–3 business days. Return-to-U.S. only, full renewal after you get home. Credit card fraud risk international? Higher than domestic — use cards with tap-to-pay over swipe where possible, never give card out of sight (restaurant takes it to kitchen, insist on terminal at table in countries where this works). STEP worth the effort? Yes — 5 minutes at step.state.gov, immediate usefulness if something goes wrong (political unrest, natural disaster, large-scale emergency).
