Planning your first international trip can feel like solving a puzzle with constantly changing pieces. After helping countless travelers navigate everything from visa applications to currency exchange, I’ve learned that success comes down to one thing: starting early and being systematic about the details.
Whether you’re heading to Europe for two weeks or backpacking through Southeast Asia for three months, this guide will walk you through exactly what you need to do (and when) to ensure your trip starts smoothly and stays that way.
Travel Documents: Start 3-6 Months Early (Seriously)
Nothing kills travel dreams faster than document issues discovered too late. Here’s what you need to know about getting your paperwork right.
Passport Reality Check
The 6-month rule catches everyone off guard. Most countries don’t just require a valid passport – they need it valid for 6 months beyond your planned return date. So if you’re returning December 1st, your passport needs to be valid until at least June 1st of the following year.
Current processing times (as of 2025):
- Standard service: 6-10 weeks ($130 for new adult passports)
- Expedited service: 2-3 weeks ($200 plus overnight shipping fees)
- Same-day service: Available at regional agencies for true emergencies ($400+)
Pro tip most people miss: Check your blank pages. Many countries require 2-3 completely blank visa pages, and immigration stamps take up more space than you’d expect.

Visa Applications: Where Atlys Actually Helps
Visa requirements change constantly, and embassy websites aren’t exactly user-friendly. This is where digital platforms like Atlys make a real difference – they track current requirements, help organize documents, and monitor application status all in one place.
Realistic processing timeframes:
- Tourist visas: 5-21 business days (not including shipping time)
- Business visas: 10-30 business days
- Work visas: 4-12 weeks depending on country
Common visa mistakes that cause delays:
- Photo specifications wrong (70% of delays stem from this)
- Bank statements older than 3 months
- Missing invitation letters or hotel confirmations
- Not accounting for embassy holidays in processing time
Budget for visa costs:
- Single-entry tourist visas: $30-200
- Multiple-entry visas: $75-400
- Express processing: Add 50-100% to base cost
- Service fees: $25-75 (worth it for complex applications)

Destination Research: Beyond Tourist Attractions
Smart research prevents culture shock and keeps you out of trouble.
Legal and Cultural Essentials
Alcohol laws vary dramatically:
- Middle Eastern countries: Often completely prohibited or heavily restricted
- Scandinavia: Legal but expensive, with specific purchasing hours
- Germany: Beer is often cheaper than water, widely available
- Southeast Asia: Usually legal but respect local customs around temples
Dress codes matter more than you think:
- Conservative countries: Long pants and covered shoulders mandatory, even in heat
- Beach destinations: Swimwear only appropriate at beach/pool areas
- Religious sites: Often require head coverings and shoe removal
Photography restrictions:
- Government buildings, military installations always off-limits
- Some countries restrict photography of people without permission
- Certain museums charge extra for photo permits
Practical Daily Life Research
Payment culture by region:
- Germany/Austria: Still heavily cash-based, especially restaurants and small shops
- Scandinavia: Nearly cashless, some places don’t accept cash at all
- Japan: Cash preferred, many places don’t take foreign cards
- Southeast Asia: Mixed – cities accept cards, rural areas cash-only
Tipping expectations:
- USA/Canada: 18-22% expected at restaurants
- Europe: 5-10% or round up to nearest euro
- Japan: Tipping can be considered rude
- Southeast Asia: Small tips appreciated but not expected
Water safety:
- Western Europe: Tap water generally safe
- Eastern Europe: Varies by country, bottled safer
- Asia/Africa/South America: Bottled water recommended
- Always research your specific destination

Financial Planning: More Than Just Budgeting
Getting your money situation right prevents major headaches abroad.
Banking Notifications and Strategy
Notify banks 2-3 weeks before departure, not 2-3 days. Include:
- Exact travel dates (add 2-3 buffer days)
- All countries you’ll visit (including connections)
- Which cards you’ll be using
Multi-card strategy that works:
- Primary card: No foreign transaction fees, chip-enabled
- Backup card: Different bank network (Visa if primary is Mastercard)
- ATM card: Linked to checking account, separate from credit cards
- Emergency card: Keep in different location, different bank entirely
International ATM Reality
Your actual costs per withdrawal:
- Your bank’s fee: $3-5 per transaction
- Foreign ATM fee: $2-8 per transaction
- Currency conversion markup: 1-3%
- Daily limits: Usually $300-500 equivalent
ATM strategy:
- Withdraw larger amounts less frequently to minimize fees
- Use bank-affiliated ATMs when possible (lower fees)
- Avoid currency conversion offers at ATMs (always choose local currency)
- Keep receipts to track exchange rates for budgeting

Travel Insurance: Don’t Skip This
Essential coverage minimums:
- Medical emergencies: $100,000+ ($250,000+ for USA destinations)
- Emergency evacuation: $1,000,000+
- Trip cancellation: Cover non-refundable expenses

- Age 70+: Add 50-100% to base rates
Accommodation and Transport: Timing Is Everything

2-3 weeks ahead:

Flight Booking Reality

Day-of-week pricing myths debunked:

- Use flexible date searches to find real deals
What actually saves money:

- Alternative airports within 2 hours
- Separate tickets for complex multi-city trips
- Booking during low-demand periods (Tuesday-Thursday departures)

Making Your International Trip Memorable
The goal of thorough preparation isn’t to eliminate all surprises – it’s creating a foundation stable enough that unexpected moments become adventures rather than emergencies.
When your documents are organized, your money situation is sorted, your health is protected, and your communication plan is ready, you’re free to embrace the spontaneous moments that make travel truly rewarding.
Tools like Atlys have revolutionized the most tedious aspects of travel planning, particularly around visa applications and document management. When administrative tasks become streamlined, you can invest energy in cultural research and experience planning that make trips genuinely transformative.
Start early, be thorough with essentials, stay flexible with details. The stories you’ll tell years later rarely involve the logistics that stressed you out during planning – but good preparation makes those stories possible in the first place.
International travel opens doors to experiences impossible at home. Those doors swing smoothest when you’ve handled the practical details with care and foresight.
