Your first trip to the United States from Colombia: what no one tells you (and saves you money and stress)

There's a sound that gives away a “first trip”: the suitcase rolling through the airport, mixed with that little voice whispering “what if I've forgotten something?”. Breathe. You don't need to become an expert in immigration. You just need smart preparation to travel calmly, spend wisely, and enjoy yourself.
Let's start with what really matters.
✈️ Your trip in one sentence
Before buying tickets, write one line: “I'm going to (city) for (X days), for tourism/a visit, and I'm staying in (area)”. It seems simple, but that sentence helps organize your budget, choose accommodation, and, most importantly, provides clarity when asked about your plans.
Quick tip: fewer cities = less logistics. You save yourself the fatigue of packing/unpacking, learning new routes every couple of days, and always being "on the go."
🛂 Visa and passport: the basics, done right
For tourism, the most common is to travel with a B1/B2 visitor visa. The official application fee is 185 USD (check before paying in case it changes).
And for your passport, the general recommendation is to travel with plenty of validity: ideally, at least six months beyond the time you plan to stay. This avoids complications with airlines or border controls.
Real-life tip: If you don't have a visa yet, avoid "non-refundable" tickets. Plan with flexible options or cancellable reservations. Your wallet will thank you.
📂 The anti-panic folder (on your phone and on paper)
It's not about carrying a library. It's about having the essentials at hand.
Create a folder on your phone and also keep a printout of the key items:
- 📍 Exact accommodation address (not "somewhere near...")
- 🎫 Exit ticket from the United States
- 🏨 Main reservations (hotel/Airbnb, internal flights if applicable)
- 🛡️ Travel insurance (not a requirement for entry, but a great decision)
- 📞 Emergency contact
If traveling with family, add children's documents and, if applicable, permits for when they are not traveling with both parents.
Tip: have everything available offline (reservations, accommodation address, and boarding passes).
But, honestly, the real "hack" is to land already connected: with Conecty you have data from minute 1 to open maps, request transportation, notify "I've arrived," and resolve any unforeseen issues without depending on airport Wi-Fi. And the best part: you can get plans from $23,000 COP (USD 6), depending on the validity you choose.
🛬 Arrival and immigration: answer like you know where you're going
Upon landing comes the "movie moment": immigration. In real life, they usually ask the basics: why you're coming, how long you're staying, where you're lodging, and how you'll pay for the trip. The key is simple: short, honest answers consistent with your plan. If they ask for support, you pull out your folder and that's it.
A tip that reduces anxiety: avoid "embellishing" the answer. You don't need to tell your life story. "I'm here for tourism for X days, staying at (address), returning on (date)" sounds accurate and sufficient.
Mini mantra: calm + clarity + consistency.

📄 A detail almost no one checks: the I-94
The I-94 is your "record of entry" into the United States: the document (now almost always digital) that confirms you entered as a visitor and, most importantly, until what date you can legally stay.
Many people believe the visa is what dictates, but in practice, the visa allows you to request entry; immigration determines your authorized stay upon entry.
This is reflected on the I-94 with a deadline: "Admit Until."
First-time traveler tip: the day after you land, check it and save it to your phone folder (screenshot or PDF).
🧳 Customs: declaring isn't getting into trouble ; it's getting out faster
Two issues cause headaches due to oversight:
- 🍎 Food: many products are restricted (especially fresh meats, fruits, and vegetables). If you declare it and it's not allowed, they'll remove it and you can proceed. If you don't declare it, then penalties can apply.
- 💵 Money: if you're traveling with more than 10,000 USD (cash or certain monetary instruments), you must declare it. Be careful if traveling with family or in a group: the total also counts.
Be careful if traveling with family or in a group: the total also counts.
🧴 The classic blunder: liquids in carry-on
At the security checkpoint, the reigning rule is 100 ml.
Liquids, gels, and aerosols must meet these conditions:
- 🧴 Containers of maximum 100 ml (3.4 oz)
- 🛍️ All in a clear, transparent bag
- 🧳 Anything exceeding that must go in checked baggage
If you are carrying medications or baby items, there are usually exceptions, but declare them at the security checkpoint to avoid delays.
💡 Tip: pack an “airport pocket” with essentials close at hand:
- 🛂 Passport
- 🎫 Boarding pass
- 🔋 Power bank
- 🎧 Headphones

💳 Money without surprises: how to create a good budget for the US (without your card exploding)
On your first trip to the United States, your budget is almost never ruined by "big" expenses. It's ruined by the invisible ones.
Taxes that appear at the end, tips, temporary holds, bank fees, and cravings.
The good news: you don't need to guess a perfect number.
- You need to organize your trip by categories.
💰 Basic Budget Checklist
✈️ Major Transportation
International and domestic flights.
🏨 Accommodation
Including taxes or additional charges.
🍽️ Meals
Estimate your daily expenses according to your travel style.
🚇 Daily Mobility
Subway, buses, airport transfers, and apps.
🎟️ Tickets and Experiences
Museums, tours, parks, and activities.
🛍️ Shopping and Indulgences
Souvenirs, clothes, and unexpected purchases.
📶 Inevitable Extras
Internet, tips, and bank fees.
Tip: for every expensive plan, include a free or cheap one (parks, walks, viewpoints, iconic neighborhoods).
💳 2) Now for it: the invisible expenses that change the game for you
Once you have the checklist, here's what separates a calm traveler from a traveler in "why is my card suffering?" mode:
💸 Why shouldn't you budget by "display price"?
The total changes at the register.
For many purchases, what you see on the tag is not the final total. Taxes are added at the register (and vary by state and city). If you make "rough" calculations based on the price you see, you might end up spending more than you thought.
Practical tip: check receipts the first few times and learn the "approximate" for your area. This habit will save you.
💵 How do tips really work in the U.S.?
In restaurants and various services, it's common to leave a tip. Don't see it as a strange expense: it's part of consumption there.
Real-life tip: check the bill, because sometimes it's already included as a "service charge" or "gratuity." If it's already included, don't pay double.
🏨 What are holds or “ghost charges”?
At hotels, it's common for them to place a hold on your card at check-in as a guarantee. It's not a definitive extra charge, but it can freeze part of your card's credit limit for a few days.
Something similar can happen at gas stations or car rental agencies.
Key tip: use a card with a good credit limit or leave room for that hold.
💳 Card or cash for travel?
For a comfortable trip, the winning formula is usually:
- 💳 Card for most purchases (safer and more practical)
- 💵 A little cash for small tips, snacks, or specific places
Tip: don't travel with just one card. Take two and keep them separate.
💱 In which currency is it better to pay when using a card?
Sometimes, when paying with a card or withdrawing from an ATM, they offer to charge you "in Colombian pesos."
It sounds convenient, but it usually ends up being more expensive due to the conversion rate they apply.
Tip: if given the choice, it's usually better to pay in dollars and let your bank handle the conversion.
🏦 Why should you notify your bank before traveling?
On a first trip, it's common for the bank to see purchases in another country and say "hmm, suspicious."
Before traveling, check:
- if your card charges a commission for international purchases
- how much it charges for ATM withdrawals
- if you need to notify them of your travel
Pro tip: save the numbers to block your card and contact the bank on your phone.
🧾 Why do you need a contingency fund?
There's always a surprise expense: extra transportation, an expensive meal due to lack of time, a jacket because you got cold, or luggage that was overweight.
If you plan to buy things in the USA, also include a budget for:
- 👟 clothes or sneakers
- 🧴 skincare
- 📱 technology
- 🎁 gifts
Practical tip: decide before you travel what you will buy and leave room for taxes or extra luggage.
Building a good budget for the USA is not about guessing a number. It's about covering your categories, anticipating invisible expenses, and leaving room to enjoy the trip without anxiety.
👨👩👧 If you're traveling with kids: quick tips to avoid chaos
First, take a full photo of them (clothes and shoes) on the day of the flight, in case you get separated in a crowded place. And agree on an easy-to-find spot: "we'll meet at the entrance of X" or "next to the information sign." It sounds exaggerated... until it isn't.
In addition to the full photo (clothes and shoes) and a clear meeting point, add this:
🧭 Anti-separation plan
A small card in their pocket with your name and number + teach them to look for "Information" or a police officer if they get lost.
You can also place an AirTag inside the tongue of one of their shoes, so you can track them always (for this, remember to always be connected to the internet with Conecty).
🍪 Smart snacks
Best to be pre-packaged and sealed. If you carry food, declare it to avoid issues at customs.
🎒 Lifesaver carry-on bag
Include a change of clothes, wipes, any medications they use, hand sanitizer, a small item for entertainment, and a light sweater (air conditioning can be surprising).
📶 Internet from minute 1
When traveling with children, the last thing you need is to struggle with Wi-Fi.
With Conecty, you land with data so you can orient yourself, get around, and calmly handle any unforeseen events.
Plans from USD $6 depending on the plan's validity.
🩺 Health and peace of mind
Traveling with up-to-date vaccinations is part of the plan, and protection against measles (MMR) is recommended.
Also save the emergency number: 911.
✨ Details that save the day
- 🧥 Bring a light sweater (air conditioning tends to be strong)
- 🌅 Take it easy on the first day: don't try to do everything right after landing
