Things to know about traveling to the USA

All information on this page is supposed to be for German tourists visiting the USA from Europe. So, for example, immigration conditions may be different for other countries.

Entering the USA as a tourist

ESTA

For German citizens, entry into the U.S. through the Visa Waver Program (ESTA) is quite simple. In addition to an approved ESTA application, you also need a valid German passport and a valid return ticket.

The Esta application can be made at the following link https://esta.cbp.dhs.gov. The forms can also be displayed in German, to be sure that you understand and fill in everything correctly. The fee for the application is $40. It can be payed either by credit card or Paypal. Approval can be immediate, but it can also take a few hours or days. So don't get impatient if it takes a little while.

However, an approved application is no guarantee that you will actually be allowed to enter the USA. The decision is made by the immigration officer on site at the respective airport of entry. ESTA is only valid for tourists and for a maximum stay of 90 days.

In 2024 we had to upload a copy/scan of our passport for the ESTA application. To make the procedure easier, we had prepared this as a JPEG-file before we started filling out the application.

APIS

The abbreviation stands for Advance Passenger Information System. This allows additional relevant passenger data to be collected by the authorities prior to flight departure. APIS data can be submitted in various ways:
- When booking a flight
- When booking a flight with the airline via an online form.
- Filling out a paper form e.g. at the check-in at the airport
In addition, we always have a printed and fully completed APIS form in our files.

Immigration and customs

At the airport of entry, you will automatically arrive at the hall where immigration to the USA takes place. Here, you will usually be directed by friendly staff to the correct lines, at the end of which you will meet the immigration officer. 

Once immigration is complete, you collect your luggage and go through customs. Everyone must go through this procedure, even if you have a connecting flight within the USA.

If you have a connecting flight, you again have to check in your luggage right after customs. Most of the time you also have to go through security again. Afterward you can head on to your new gate to continue your flight. For such a connecting flight in the USA we would recommend to plan at least 2 hours time.

MPC

Mobile Passport Control (MPC) allows eligible travelers to submit their travel document, photo, and customs declaration information through a free, secure app on their smartphone or other mobile device. The use of MPC streamlines the traveler’s entry process into the United States by reducing passport control inspection time and overall wait time. Use of MPC does not require pre-approval. Travelers who successfully use the MPC app will no longer have to complete a paper form and may be provided a designated queue. As a result, travelers may experience shorter wait times, less congestion and efficient processing.

Before the trip: Download the app. Create persons for entry. Up to 12 people can be registered for entry. The app is self-explanatory. It describes exactly what you need to do. The answer to the question which terminal your plane is arriving at can be found on the airport's website. If everything has been entered and answered correctly, a page will appear asking whether you have arrived at the respective airport in the USA. Once you have completed this page, you can close the app and forget about it until you arrive.
After arriving in the USA: Once you arrive, you confirm in the app that you have reached the airport. You then need to take a recent photo of each registered traveler. Finally, you submit everything. A page will appear on your smartphone asking you to go to one of the MPC lanes. Now you have 4 hours to do so. A timer will run at the top of your device.

In our own experience and the experience of our friends, the app works without any problems. There are not always MPC lines available, in which case you still have to wait in the regular long queues. If the MPC lines are open, entry is much quicker. Everything you need to know about entering the country with MPC can be found here..

Time zones

EST (Eastern Standard Time), CST (Central Standard Time), MST (Mountain Standard Time), PST (Pacific Standard Time), AKST (Alaskan Standard Time), HST (Hawaiian Standard Time)

In the USA, too, the time is changed from winter to summer time. But it's not as simple as it sounds.

The time is normally changed to daylight saving time on the second Sunday in March and back to winter time on the first Sunday in November. However, this changeover only occurs on the continent. Alaska and Hawaii do not change the time.

....The exception on the continent is Arizona. Here, the time is also not changed over. To make things a little more complicated, the Navajo Nation, which is located in Arizona, already changes its clocks to daylight saving time.

Winter time is referred to as Standard Time, and summer time is referred to as Daylight Saving Time (DST).

In 2026, clocks will change to Daylight Saving Time on March 8 and to Standard Time on November 1.

Public holidays

A few comments about the holidays in the US:

Since there are only very few holidays in the U.S. and the average employee has far fewer vacation days than we are used to in Germany, the few days off, especially around the holidays, are of course used extensively. 

As a result, it is very crowded almost everywhere on these holidays and also on the weekends before. We would recommend everyone to stay away from big cities, national parks, national monuments, state parks etc. especially on Memorial and Labor Day and the weekends before. Especially in the parks it will be more than crowded on these days and the enjoyment of nature is completely lost. It is possible that you can't visit certain places at all, simply because certain locations are so crowded.

Two examples:
Memorial Day 2013 in Yosemite NP. We didn't even drive into the Valley, because there was already traffic jam at the entrance. We tried it then with the Glacier Point. But since there was a waiting time of 2 hours, just to be able to go up, we left without having achieved anything.
Memorial Day 2017 in Chicago. The wait to get on the Willis Tower was 7 hours!!!! and that's not a joke or an exaggeration. The only day of the year when it is supposed to be worse is the 4th of July. But we didn't check that. Also the wait to get into one of the balconies with the glass floors was another hour. So nothing you necessarily need again.

Another recommendation would be to book rooms well in advance if you plan to stay somewhere near attractions. That the prices on holiday weekends are correspondingly higher does not need to be mentioned.

Phone and Internet on the Road

Until our 2019 vacation in California, we never used a SIM card during our vacation. Somehow we never needed it, because you have free wifi in almost every hotel and now there are also free hotspots in almost every store, restaurant and coffee shop. 

We would still say that you don't really need an US-SIM card, but we have certainly experienced the advantages of it. The biggest advantage for us is navigating with our cell phone. This saved us the additional cost of an extra navigation device. That alone paid off the cost of the SIM card. Another nice gimmick is the fact that you can use WhatsApp with your German number, even if you get your own American number. I had fun chatting with home on long car journeys and sending the latest photos. Of the 4GB available to us with our first card, we didn't even use up half of the volume with navigation, phone calls and surfing during our four-week vacation. 

There is now an abundance of prepaid SIM cards and eSIMS from various providers. We prefer physical cards and always buy them before we go on vacation.
